Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616762, here are decompositions:

13 + 31616749 = 31616762
139 + 31616623 = 31616762
193 + 31616569 = 31616762
223 + 31616539 = 31616762
241 + 31616521 = 31616762
283 + 31616479 = 31616762
613 + 31616149 = 31616762
739 + 31616023 = 31616762

Showing the first eight; more decompositions exist.
