Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609492, here are decompositions:

11 + 31609481 = 31609492
23 + 31609469 = 31609492
29 + 31609463 = 31609492
41 + 31609451 = 31609492
263 + 31609229 = 31609492
269 + 31609223 = 31609492
401 + 31609091 = 31609492
443 + 31609049 = 31609492

Showing the first eight; more decompositions exist.
