Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496284, here are decompositions:

23 + 31496261 = 31496284
227 + 31496057 = 31496284
257 + 31496027 = 31496284
593 + 31495691 = 31496284
683 + 31495601 = 31496284
761 + 31495523 = 31496284
773 + 31495511 = 31496284
821 + 31495463 = 31496284

Showing the first eight; more decompositions exist.
