Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617726, here are decompositions:

23 + 8617703 = 8617726
179 + 8617547 = 8617726
353 + 8617373 = 8617726
449 + 8617277 = 8617726
617 + 8617109 = 8617726
653 + 8617073 = 8617726
809 + 8616917 = 8617726
839 + 8616887 = 8617726

Showing the first eight; more decompositions exist.
