Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529214, here are decompositions:

47 + 31529167 = 31529214
107 + 31529107 = 31529214
127 + 31529087 = 31529214
373 + 31528841 = 31529214
383 + 31528831 = 31529214
401 + 31528813 = 31529214
463 + 31528751 = 31529214
491 + 31528723 = 31529214

Showing the first eight; more decompositions exist.
