Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609534, here are decompositions:

3 + 31609531 = 31609534
41 + 31609493 = 31609534
53 + 31609481 = 31609534
71 + 31609463 = 31609534
83 + 31609451 = 31609534
311 + 31609223 = 31609534
443 + 31609091 = 31609534
503 + 31609031 = 31609534

Showing the first eight; more decompositions exist.
