Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607354, here are decompositions:

13 + 31607341 = 31607354
61 + 31607293 = 31607354
73 + 31607281 = 31607354
127 + 31607227 = 31607354
307 + 31607047 = 31607354
397 + 31606957 = 31607354
601 + 31606753 = 31607354
613 + 31606741 = 31607354

Showing the first eight; more decompositions exist.
