Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529414, here are decompositions:

61 + 31529353 = 31529414
67 + 31529347 = 31529414
157 + 31529257 = 31529414
307 + 31529107 = 31529414
421 + 31528993 = 31529414
571 + 31528843 = 31529414
601 + 31528813 = 31529414
607 + 31528807 = 31529414

Showing the first eight; more decompositions exist.
