Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500536, here are decompositions:

7 + 31500529 = 31500536
73 + 31500463 = 31500536
79 + 31500457 = 31500536
157 + 31500379 = 31500536
349 + 31500187 = 31500536
547 + 31499989 = 31500536
643 + 31499893 = 31500536
673 + 31499863 = 31500536

Showing the first eight; more decompositions exist.
