Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476738, here are decompositions:

5 + 31476733 = 31476738
11 + 31476727 = 31476738
47 + 31476691 = 31476738
107 + 31476631 = 31476738
127 + 31476611 = 31476738
131 + 31476607 = 31476738
151 + 31476587 = 31476738
191 + 31476547 = 31476738

Showing the first eight; more decompositions exist.
