Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476862, here are decompositions:

41 + 31476821 = 31476862
239 + 31476623 = 31476862
251 + 31476611 = 31476862
269 + 31476593 = 31476862
311 + 31476551 = 31476862
353 + 31476509 = 31476862
401 + 31476461 = 31476862
449 + 31476413 = 31476862

Showing the first eight; more decompositions exist.
