Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520762, here are decompositions:

43 + 31520719 = 31520762
61 + 31520701 = 31520762
103 + 31520659 = 31520762
181 + 31520581 = 31520762
193 + 31520569 = 31520762
271 + 31520491 = 31520762
283 + 31520479 = 31520762
373 + 31520389 = 31520762

Showing the first eight; more decompositions exist.
