Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616770, here are decompositions:

23 + 31616747 = 31616770
41 + 31616729 = 31616770
83 + 31616687 = 31616770
167 + 31616603 = 31616770
191 + 31616579 = 31616770
347 + 31616423 = 31616770
359 + 31616411 = 31616770
389 + 31616381 = 31616770

Showing the first eight; more decompositions exist.
