Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617362, here are decompositions:

79 + 31617283 = 31617362
109 + 31617253 = 31617362
163 + 31617199 = 31617362
181 + 31617181 = 31617362
229 + 31617133 = 31617362
313 + 31617049 = 31617362
349 + 31617013 = 31617362
433 + 31616929 = 31617362

Showing the first eight; more decompositions exist.
