Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529924, here are decompositions:

43 + 31529881 = 31529924
331 + 31529593 = 31529924
367 + 31529557 = 31529924
373 + 31529551 = 31529924
571 + 31529353 = 31529924
577 + 31529347 = 31529924
757 + 31529167 = 31529924
1093 + 31528831 = 31529924

Showing the first eight; more decompositions exist.
