Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609702, here are decompositions:

11 + 31609691 = 31609702
23 + 31609679 = 31609702
41 + 31609661 = 31609702
71 + 31609631 = 31609702
233 + 31609469 = 31609702
239 + 31609463 = 31609702
251 + 31609451 = 31609702
479 + 31609223 = 31609702

Showing the first eight; more decompositions exist.
