Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476774, here are decompositions:

31 + 31476743 = 31476774
41 + 31476733 = 31476774
47 + 31476727 = 31476774
71 + 31476703 = 31476774
83 + 31476691 = 31476774
151 + 31476623 = 31476774
163 + 31476611 = 31476774
167 + 31476607 = 31476774

Showing the first eight; more decompositions exist.
