Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614972, here are decompositions:

19 + 31614953 = 31614972
29 + 31614943 = 31614972
31 + 31614941 = 31614972
43 + 31614929 = 31614972
73 + 31614899 = 31614972
83 + 31614889 = 31614972
113 + 31614859 = 31614972
139 + 31614833 = 31614972

Showing the first eight; more decompositions exist.
