Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614930, here are decompositions:

31 + 31614899 = 31614930
41 + 31614889 = 31614930
71 + 31614859 = 31614930
79 + 31614851 = 31614930
97 + 31614833 = 31614930
101 + 31614829 = 31614930
197 + 31614733 = 31614930
223 + 31614707 = 31614930

Showing the first eight; more decompositions exist.
