Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529504, here are decompositions:

73 + 31529431 = 31529504
151 + 31529353 = 31529504
157 + 31529347 = 31529504
337 + 31529167 = 31529504
397 + 31529107 = 31529504
661 + 31528843 = 31529504
673 + 31528831 = 31529504
691 + 31528813 = 31529504

Showing the first eight; more decompositions exist.
