Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528790, here are decompositions:

61 + 31528729 = 31528790
67 + 31528723 = 31528790
157 + 31528633 = 31528790
211 + 31528579 = 31528790
331 + 31528459 = 31528790
463 + 31528327 = 31528790
499 + 31528291 = 31528790
523 + 31528267 = 31528790

Showing the first eight; more decompositions exist.
