Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540596, here are decompositions:

23 + 31540573 = 31540596
67 + 31540529 = 31540596
97 + 31540499 = 31540596
103 + 31540493 = 31540596
107 + 31540489 = 31540596
179 + 31540417 = 31540596
233 + 31540363 = 31540596
257 + 31540339 = 31540596

Showing the first eight; more decompositions exist.
