Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588276, here are decompositions:

23 + 31588253 = 31588276
29 + 31588247 = 31588276
173 + 31588103 = 31588276
257 + 31588019 = 31588276
353 + 31587923 = 31588276
383 + 31587893 = 31588276
509 + 31587767 = 31588276
569 + 31587707 = 31588276

Showing the first eight; more decompositions exist.
