Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614970, here are decompositions:

17 + 31614953 = 31614970
29 + 31614941 = 31614970
41 + 31614929 = 31614970
71 + 31614899 = 31614970
89 + 31614881 = 31614970
131 + 31614839 = 31614970
137 + 31614833 = 31614970
173 + 31614797 = 31614970

Showing the first eight; more decompositions exist.
