Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616122, here are decompositions:

53 + 31616069 = 31616122
89 + 31616033 = 31616122
101 + 31616021 = 31616122
113 + 31616009 = 31616122
149 + 31615973 = 31616122
359 + 31615763 = 31616122
683 + 31615439 = 31616122
719 + 31615403 = 31616122

Showing the first eight; more decompositions exist.
