Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605632, here are decompositions:

13 + 31605619 = 31605632
61 + 31605571 = 31605632
193 + 31605439 = 31605632
271 + 31605361 = 31605632
283 + 31605349 = 31605632
313 + 31605319 = 31605632
463 + 31605169 = 31605632
523 + 31605109 = 31605632

Showing the first eight; more decompositions exist.
