Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616822, here are decompositions:

73 + 31616749 = 31616822
151 + 31616671 = 31616822
199 + 31616623 = 31616822
283 + 31616539 = 31616822
313 + 31616509 = 31616822
421 + 31616401 = 31616822
463 + 31616359 = 31616822
541 + 31616281 = 31616822

Showing the first eight; more decompositions exist.
