Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617266, here are decompositions:

13 + 31617253 = 31617266
67 + 31617199 = 31617266
193 + 31617073 = 31617266
337 + 31616929 = 31617266
349 + 31616917 = 31617266
379 + 31616887 = 31617266
409 + 31616857 = 31617266
619 + 31616647 = 31617266

Showing the first eight; more decompositions exist.
