Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616962, here are decompositions:

11 + 31616951 = 31616962
29 + 31616933 = 31616962
59 + 31616903 = 31616962
71 + 31616891 = 31616962
233 + 31616729 = 31616962
269 + 31616693 = 31616962
359 + 31616603 = 31616962
383 + 31616579 = 31616962

Showing the first eight; more decompositions exist.
