Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616892, here are decompositions:

5 + 31616887 = 31616892
53 + 31616839 = 31616892
163 + 31616729 = 31616892
199 + 31616693 = 31616892
269 + 31616623 = 31616892
313 + 31616579 = 31616892
331 + 31616561 = 31616892
353 + 31616539 = 31616892

Showing the first eight; more decompositions exist.
