Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616462, here are decompositions:

43 + 31616419 = 31616462
61 + 31616401 = 31616462
103 + 31616359 = 31616462
181 + 31616281 = 31616462
211 + 31616251 = 31616462
313 + 31616149 = 31616462
349 + 31616113 = 31616462
421 + 31616041 = 31616462

Showing the first eight; more decompositions exist.
