Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499832, here are decompositions:

29 + 31499803 = 31499832
71 + 31499761 = 31499832
101 + 31499731 = 31499832
173 + 31499659 = 31499832
211 + 31499621 = 31499832
233 + 31499599 = 31499832
239 + 31499593 = 31499832
271 + 31499561 = 31499832

Showing the first eight; more decompositions exist.
