Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536674, here are decompositions:

61 + 31536613 = 31536674
67 + 31536607 = 31536674
193 + 31536481 = 31536674
271 + 31536403 = 31536674
277 + 31536397 = 31536674
283 + 31536391 = 31536674
313 + 31536361 = 31536674
487 + 31536187 = 31536674

Showing the first eight; more decompositions exist.
