Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616262, here are decompositions:

5 + 31616257 = 31616262
11 + 31616251 = 31616262
31 + 31616231 = 31616262
43 + 31616219 = 31616262
79 + 31616183 = 31616262
89 + 31616173 = 31616262
113 + 31616149 = 31616262
149 + 31616113 = 31616262

Showing the first eight; more decompositions exist.
