Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499612, here are decompositions:

13 + 31499599 = 31499612
19 + 31499593 = 31499612
181 + 31499431 = 31499612
211 + 31499401 = 31499612
229 + 31499383 = 31499612
241 + 31499371 = 31499612
271 + 31499341 = 31499612
283 + 31499329 = 31499612

Showing the first eight; more decompositions exist.
