Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487596, here are decompositions:

53 + 31487543 = 31487596
83 + 31487513 = 31487596
89 + 31487507 = 31487596
149 + 31487447 = 31487596
227 + 31487369 = 31487596
233 + 31487363 = 31487596
317 + 31487279 = 31487596
443 + 31487153 = 31487596

Showing the first eight; more decompositions exist.
