Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609468, here are decompositions:

5 + 31609463 = 31609468
17 + 31609451 = 31609468
179 + 31609289 = 31609468
239 + 31609229 = 31609468
389 + 31609079 = 31609468
419 + 31609049 = 31609468
509 + 31608959 = 31609468
557 + 31608911 = 31609468

Showing the first eight; more decompositions exist.
