Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617122, here are decompositions:

73 + 31617049 = 31617122
109 + 31617013 = 31617122
193 + 31616929 = 31617122
283 + 31616839 = 31617122
349 + 31616773 = 31617122
373 + 31616749 = 31617122
499 + 31616623 = 31617122
601 + 31616521 = 31617122

Showing the first eight; more decompositions exist.
