Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540902, here are decompositions:

31 + 31540871 = 31540902
79 + 31540823 = 31540902
89 + 31540813 = 31540902
179 + 31540723 = 31540902
193 + 31540709 = 31540902
223 + 31540679 = 31540902
233 + 31540669 = 31540902
251 + 31540651 = 31540902

Showing the first eight; more decompositions exist.
