Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511596, here are decompositions:

47 + 31511549 = 31511596
59 + 31511537 = 31511596
113 + 31511483 = 31511596
173 + 31511423 = 31511596
269 + 31511327 = 31511596
383 + 31511213 = 31511596
449 + 31511147 = 31511596
593 + 31511003 = 31511596

Showing the first eight; more decompositions exist.
