Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476798, here are decompositions:

71 + 31476727 = 31476798
107 + 31476691 = 31476798
167 + 31476631 = 31476798
191 + 31476607 = 31476798
211 + 31476587 = 31476798
251 + 31476547 = 31476798
281 + 31476517 = 31476798
337 + 31476461 = 31476798

Showing the first eight; more decompositions exist.
