Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476770, here are decompositions:

37 + 31476733 = 31476770
43 + 31476727 = 31476770
67 + 31476703 = 31476770
79 + 31476691 = 31476770
139 + 31476631 = 31476770
163 + 31476607 = 31476770
223 + 31476547 = 31476770
271 + 31476499 = 31476770

Showing the first eight; more decompositions exist.
