Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529144, here are decompositions:

37 + 31529107 = 31529144
151 + 31528993 = 31529144
313 + 31528831 = 31529144
331 + 31528813 = 31529144
337 + 31528807 = 31529144
421 + 31528723 = 31529144
523 + 31528621 = 31529144
571 + 31528573 = 31529144

Showing the first eight; more decompositions exist.
