Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500584, here are decompositions:

97 + 31500487 = 31500584
127 + 31500457 = 31500584
223 + 31500361 = 31500584
397 + 31500187 = 31500584
691 + 31499893 = 31500584
751 + 31499833 = 31500584
823 + 31499761 = 31500584
853 + 31499731 = 31500584

Showing the first eight; more decompositions exist.
