Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617326, here are decompositions:

43 + 31617283 = 31617326
73 + 31617253 = 31617326
127 + 31617199 = 31617326
193 + 31617133 = 31617326
277 + 31617049 = 31617326
313 + 31617013 = 31617326
397 + 31616929 = 31617326
409 + 31616917 = 31617326

Showing the first eight; more decompositions exist.
