Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491596, here are decompositions:

7 + 31491589 = 31491596
127 + 31491469 = 31491596
307 + 31491289 = 31491596
313 + 31491283 = 31491596
397 + 31491199 = 31491596
607 + 31490989 = 31491596
613 + 31490983 = 31491596
739 + 31490857 = 31491596

Showing the first eight; more decompositions exist.
