Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512598, here are decompositions:

11 + 31512587 = 31512598
41 + 31512557 = 31512598
239 + 31512359 = 31512598
251 + 31512347 = 31512598
389 + 31512209 = 31512598
479 + 31512119 = 31512598
587 + 31512011 = 31512598
617 + 31511981 = 31512598

Showing the first eight; more decompositions exist.
