Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616958, here are decompositions:

7 + 31616951 = 31616958
29 + 31616929 = 31616958
41 + 31616917 = 31616958
67 + 31616891 = 31616958
71 + 31616887 = 31616958
101 + 31616857 = 31616958
211 + 31616747 = 31616958
229 + 31616729 = 31616958

Showing the first eight; more decompositions exist.
