Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617098, here are decompositions:

181 + 31616917 = 31617098
211 + 31616887 = 31617098
241 + 31616857 = 31617098
349 + 31616749 = 31617098
421 + 31616677 = 31617098
577 + 31616521 = 31617098
619 + 31616479 = 31617098
739 + 31616359 = 31617098

Showing the first eight; more decompositions exist.
