Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605056, here are decompositions:

37 + 31605019 = 31605056
97 + 31604959 = 31605056
193 + 31604863 = 31605056
313 + 31604743 = 31605056
337 + 31604719 = 31605056
367 + 31604689 = 31605056
409 + 31604647 = 31605056
499 + 31604557 = 31605056

Showing the first eight; more decompositions exist.
