Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520852, here are decompositions:

151 + 31520701 = 31520852
193 + 31520659 = 31520852
271 + 31520581 = 31520852
283 + 31520569 = 31520852
373 + 31520479 = 31520852
463 + 31520389 = 31520852
499 + 31520353 = 31520852
619 + 31520233 = 31520852

Showing the first eight; more decompositions exist.
