Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500182, here are decompositions:

193 + 31499989 = 31500182
283 + 31499899 = 31500182
349 + 31499833 = 31500182
379 + 31499803 = 31500182
421 + 31499761 = 31500182
523 + 31499659 = 31500182
691 + 31499491 = 31500182
751 + 31499431 = 31500182

Showing the first eight; more decompositions exist.
