Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511496, here are decompositions:

13 + 31511483 = 31511496
19 + 31511477 = 31511496
59 + 31511437 = 31511496
73 + 31511423 = 31511496
283 + 31511213 = 31511496
307 + 31511189 = 31511496
349 + 31511147 = 31511496
353 + 31511143 = 31511496

Showing the first eight; more decompositions exist.
