Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529882, here are decompositions:

211 + 31529671 = 31529882
331 + 31529551 = 31529882
523 + 31529359 = 31529882
613 + 31529269 = 31529882
733 + 31529149 = 31529882
829 + 31529053 = 31529882
1039 + 31528843 = 31529882
1051 + 31528831 = 31529882

Showing the first eight; more decompositions exist.
