Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476790, here are decompositions:

47 + 31476743 = 31476790
167 + 31476623 = 31476790
179 + 31476611 = 31476790
197 + 31476593 = 31476790
239 + 31476551 = 31476790
281 + 31476509 = 31476790
353 + 31476437 = 31476790
419 + 31476371 = 31476790

Showing the first eight; more decompositions exist.
