Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476814, here are decompositions:

71 + 31476743 = 31476814
191 + 31476623 = 31476814
227 + 31476587 = 31476814
263 + 31476551 = 31476814
353 + 31476461 = 31476814
401 + 31476413 = 31476814
431 + 31476383 = 31476814
443 + 31476371 = 31476814

Showing the first eight; more decompositions exist.
