Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500482, here are decompositions:

19 + 31500463 = 31500482
31 + 31500451 = 31500482
103 + 31500379 = 31500482
619 + 31499863 = 31500482
751 + 31499731 = 31500482
823 + 31499659 = 31500482
883 + 31499599 = 31500482
991 + 31499491 = 31500482

Showing the first eight; more decompositions exist.
