Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609692, here are decompositions:

13 + 31609679 = 31609692
31 + 31609661 = 31609692
61 + 31609631 = 31609692
83 + 31609609 = 31609692
109 + 31609583 = 31609692
131 + 31609561 = 31609692
151 + 31609541 = 31609692
173 + 31609519 = 31609692

Showing the first eight; more decompositions exist.
