Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588246, here are decompositions:

47 + 31588199 = 31588246
89 + 31588157 = 31588246
227 + 31588019 = 31588246
353 + 31587893 = 31588246
467 + 31587779 = 31588246
479 + 31587767 = 31588246
509 + 31587737 = 31588246
587 + 31587659 = 31588246

Showing the first eight; more decompositions exist.
