Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598776, here are decompositions:

5 + 31598771 = 31598776
23 + 31598753 = 31598776
59 + 31598717 = 31598776
89 + 31598687 = 31598776
107 + 31598669 = 31598776
233 + 31598543 = 31598776
239 + 31598537 = 31598776
257 + 31598519 = 31598776

Showing the first eight; more decompositions exist.
