Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476744, here are decompositions:

11 + 31476733 = 31476744
17 + 31476727 = 31476744
41 + 31476703 = 31476744
53 + 31476691 = 31476744
113 + 31476631 = 31476744
137 + 31476607 = 31476744
151 + 31476593 = 31476744
157 + 31476587 = 31476744

Showing the first eight; more decompositions exist.
