Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476672, here are decompositions:

41 + 31476631 = 31476672
61 + 31476611 = 31476672
79 + 31476593 = 31476672
163 + 31476509 = 31476672
173 + 31476499 = 31476672
211 + 31476461 = 31476672
223 + 31476449 = 31476672
239 + 31476433 = 31476672

Showing the first eight; more decompositions exist.
