Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529374, here are decompositions:

53 + 31529321 = 31529374
101 + 31529273 = 31529374
131 + 31529243 = 31529374
293 + 31529081 = 31529374
521 + 31528853 = 31529374
563 + 31528811 = 31529374
677 + 31528697 = 31529374
761 + 31528613 = 31529374

Showing the first eight; more decompositions exist.
