Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726636, here are decompositions:

3 + 8726633 = 8726636
67 + 8726569 = 8726636
103 + 8726533 = 8726636
109 + 8726527 = 8726636
157 + 8726479 = 8726636
277 + 8726359 = 8726636
307 + 8726329 = 8726636
313 + 8726323 = 8726636

Showing the first eight; more decompositions exist.
