Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616342, here are decompositions:

3 + 31616339 = 31616342
61 + 31616281 = 31616342
193 + 31616149 = 31616342
229 + 31616113 = 31616342
283 + 31616059 = 31616342
349 + 31615993 = 31616342
421 + 31615921 = 31616342
601 + 31615741 = 31616342

Showing the first eight; more decompositions exist.
