Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616756, here are decompositions:

7 + 31616749 = 31616756
79 + 31616677 = 31616756
109 + 31616647 = 31616756
277 + 31616479 = 31616756
337 + 31616419 = 31616756
397 + 31616359 = 31616756
499 + 31616257 = 31616756
607 + 31616149 = 31616756

Showing the first eight; more decompositions exist.
