Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609562, here are decompositions:

13 + 31609549 = 31609562
31 + 31609531 = 31609562
43 + 31609519 = 31609562
109 + 31609453 = 31609562
181 + 31609381 = 31609562
223 + 31609339 = 31609562
331 + 31609231 = 31609562
349 + 31609213 = 31609562

Showing the first eight; more decompositions exist.
