Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555674, here are decompositions:

11 + 31555663 = 31555674
13 + 31555661 = 31555674
23 + 31555651 = 31555674
41 + 31555633 = 31555674
43 + 31555631 = 31555674
67 + 31555607 = 31555674
71 + 31555603 = 31555674
103 + 31555571 = 31555674

Showing the first eight; more decompositions exist.
