Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499610, here are decompositions:

11 + 31499599 = 31499610
17 + 31499593 = 31499610
73 + 31499537 = 31499610
113 + 31499497 = 31499610
151 + 31499459 = 31499610
179 + 31499431 = 31499610
199 + 31499411 = 31499610
211 + 31499399 = 31499610

Showing the first eight; more decompositions exist.
