Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605134, here are decompositions:

7 + 31605127 = 31605134
37 + 31605097 = 31605134
61 + 31605073 = 31605134
271 + 31604863 = 31605134
331 + 31604803 = 31605134
367 + 31604767 = 31605134
487 + 31604647 = 31605134
523 + 31604611 = 31605134

Showing the first eight; more decompositions exist.
