Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476794, here are decompositions:

61 + 31476733 = 31476794
67 + 31476727 = 31476794
103 + 31476691 = 31476794
163 + 31476631 = 31476794
277 + 31476517 = 31476794
337 + 31476457 = 31476794
421 + 31476373 = 31476794
607 + 31476187 = 31476794

Showing the first eight; more decompositions exist.
