Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476678, here are decompositions:

47 + 31476631 = 31476678
67 + 31476611 = 31476678
71 + 31476607 = 31476678
127 + 31476551 = 31476678
131 + 31476547 = 31476678
179 + 31476499 = 31476678
227 + 31476451 = 31476678
229 + 31476449 = 31476678

Showing the first eight; more decompositions exist.
