Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616970, here are decompositions:

19 + 31616951 = 31616970
37 + 31616933 = 31616970
41 + 31616929 = 31616970
53 + 31616917 = 31616970
67 + 31616903 = 31616970
79 + 31616891 = 31616970
83 + 31616887 = 31616970
113 + 31616857 = 31616970

Showing the first eight; more decompositions exist.
