Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609524, here are decompositions:

5 + 31609519 = 31609524
31 + 31609493 = 31609524
43 + 31609481 = 31609524
61 + 31609463 = 31609524
71 + 31609453 = 31609524
73 + 31609451 = 31609524
131 + 31609393 = 31609524
257 + 31609267 = 31609524

Showing the first eight; more decompositions exist.
