Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614946, here are decompositions:

3 + 31614943 = 31614946
5 + 31614941 = 31614946
17 + 31614929 = 31614946
47 + 31614899 = 31614946
107 + 31614839 = 31614946
113 + 31614833 = 31614946
149 + 31614797 = 31614946
239 + 31614707 = 31614946

Showing the first eight; more decompositions exist.
