Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520792, here are decompositions:

31 + 31520761 = 31520792
73 + 31520719 = 31520792
211 + 31520581 = 31520792
223 + 31520569 = 31520792
283 + 31520509 = 31520792
313 + 31520479 = 31520792
421 + 31520371 = 31520792
439 + 31520353 = 31520792

Showing the first eight; more decompositions exist.
