Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520796, here are decompositions:

137 + 31520659 = 31520796
179 + 31520617 = 31520796
227 + 31520569 = 31520796
269 + 31520527 = 31520796
277 + 31520519 = 31520796
313 + 31520483 = 31520796
317 + 31520479 = 31520796
379 + 31520417 = 31520796

Showing the first eight; more decompositions exist.
