Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617722, here are decompositions:

43 + 31617679 = 31617722
139 + 31617583 = 31617722
163 + 31617559 = 31617722
193 + 31617529 = 31617722
229 + 31617493 = 31617722
313 + 31617409 = 31617722
349 + 31617373 = 31617722
439 + 31617283 = 31617722

Showing the first eight; more decompositions exist.
