Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499616, here are decompositions:

17 + 31499599 = 31499616
23 + 31499593 = 31499616
79 + 31499537 = 31499616
149 + 31499467 = 31499616
157 + 31499459 = 31499616
229 + 31499387 = 31499616
233 + 31499383 = 31499616
293 + 31499323 = 31499616

Showing the first eight; more decompositions exist.
