Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529176, here are decompositions:

89 + 31529087 = 31529176
179 + 31528997 = 31529176
353 + 31528823 = 31529176
479 + 31528697 = 31529176
563 + 31528613 = 31529176
617 + 31528559 = 31529176
677 + 31528499 = 31529176
743 + 31528433 = 31529176

Showing the first eight; more decompositions exist.
