Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616758, here are decompositions:

11 + 31616747 = 31616758
29 + 31616729 = 31616758
71 + 31616687 = 31616758
179 + 31616579 = 31616758
197 + 31616561 = 31616758
347 + 31616411 = 31616758
389 + 31616369 = 31616758
419 + 31616339 = 31616758

Showing the first eight; more decompositions exist.
