Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500014, here are decompositions:

151 + 31499863 = 31500014
181 + 31499833 = 31500014
211 + 31499803 = 31500014
283 + 31499731 = 31500014
421 + 31499593 = 31500014
523 + 31499491 = 31500014
547 + 31499467 = 31500014
607 + 31499407 = 31500014

Showing the first eight; more decompositions exist.
