Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597372, here are decompositions:

5 + 31597367 = 31597372
89 + 31597283 = 31597372
173 + 31597199 = 31597372
251 + 31597121 = 31597372
449 + 31596923 = 31597372
491 + 31596881 = 31597372
659 + 31596713 = 31597372
701 + 31596671 = 31597372

Showing the first eight; more decompositions exist.
