Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476758, here are decompositions:

31 + 31476727 = 31476758
67 + 31476691 = 31476758
127 + 31476631 = 31476758
151 + 31476607 = 31476758
211 + 31476547 = 31476758
241 + 31476517 = 31476758
307 + 31476451 = 31476758
367 + 31476391 = 31476758

Showing the first eight; more decompositions exist.
