Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614948, here are decompositions:

5 + 31614943 = 31614948
7 + 31614941 = 31614948
19 + 31614929 = 31614948
59 + 31614889 = 31614948
67 + 31614881 = 31614948
89 + 31614859 = 31614948
97 + 31614851 = 31614948
109 + 31614839 = 31614948

Showing the first eight; more decompositions exist.
