Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609486, here are decompositions:

5 + 31609481 = 31609486
17 + 31609469 = 31609486
23 + 31609463 = 31609486
197 + 31609289 = 31609486
257 + 31609229 = 31609486
263 + 31609223 = 31609486
569 + 31608917 = 31609486
593 + 31608893 = 31609486

Showing the first eight; more decompositions exist.
