Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617706, here are decompositions:

17 + 31617689 = 31617706
47 + 31617659 = 31617706
173 + 31617533 = 31617706
257 + 31617449 = 31617706
293 + 31617413 = 31617706
467 + 31617239 = 31617706
557 + 31617149 = 31617706
677 + 31617029 = 31617706

Showing the first eight; more decompositions exist.
