Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499924, here are decompositions:

3 + 31499921 = 31499924
31 + 31499893 = 31499924
61 + 31499863 = 31499924
163 + 31499761 = 31499924
193 + 31499731 = 31499924
331 + 31499593 = 31499924
433 + 31499491 = 31499924
457 + 31499467 = 31499924

Showing the first eight; more decompositions exist.
