Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499624, here are decompositions:

3 + 31499621 = 31499624
31 + 31499593 = 31499624
127 + 31499497 = 31499624
157 + 31499467 = 31499624
193 + 31499431 = 31499624
223 + 31499401 = 31499624
241 + 31499383 = 31499624
283 + 31499341 = 31499624

Showing the first eight; more decompositions exist.
