Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605662, here are decompositions:

43 + 31605619 = 31605662
79 + 31605583 = 31605662
223 + 31605439 = 31605662
313 + 31605349 = 31605662
433 + 31605229 = 31605662
523 + 31605139 = 31605662
643 + 31605019 = 31605662
661 + 31605001 = 31605662

Showing the first eight; more decompositions exist.
