Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619776, here are decompositions:

5 + 31619771 = 31619776
17 + 31619759 = 31619776
53 + 31619723 = 31619776
59 + 31619717 = 31619776
107 + 31619669 = 31619776
173 + 31619603 = 31619776
233 + 31619543 = 31619776
257 + 31619519 = 31619776

Showing the first eight; more decompositions exist.
