Maths Textbook Question

A mathematician proposed that "Every even number greater than 2 can be expressed as a sum of two prime numbers." Do you agree? Why?

I agree. Because...

4 = 2+2
6 = 3+3
8 = 3+5
10 = 5+5
12 = 5+7
14 = 7+7
16 = 3+13
18 = 5+13
20 = 7+13
22 = 5+17
24 = 7+17
26 = 7+19
28 = 5+23
30 = 7+23
32 = 3+29
34 = 17+17
36 = 31+5
38 = 31+7
40 = 37+3
42 = 37+5
44 = 41+3
46 = 41+5 since it still works until 46...

it might just work for the others :D
