Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614738, here are decompositions:

5 + 31614733 = 31614738
31 + 31614707 = 31614738
37 + 31614701 = 31614738
41 + 31614697 = 31614738
61 + 31614677 = 31614738
97 + 31614641 = 31614738
107 + 31614631 = 31614738
137 + 31614601 = 31614738

Showing the first eight; more decompositions exist.
