Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609126, here are decompositions:

47 + 31609079 = 31609126
167 + 31608959 = 31609126
173 + 31608953 = 31609126
233 + 31608893 = 31609126
239 + 31608887 = 31609126
347 + 31608779 = 31609126
389 + 31608737 = 31609126
599 + 31608527 = 31609126

Showing the first eight; more decompositions exist.
