Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616068, here are decompositions:

47 + 31616021 = 31616068
59 + 31616009 = 31616068
89 + 31615979 = 31616068
149 + 31615919 = 31616068
311 + 31615757 = 31616068
479 + 31615589 = 31616068
677 + 31615391 = 31616068
839 + 31615229 = 31616068

Showing the first eight; more decompositions exist.
