Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726656, here are decompositions:

23 + 8726633 = 8726656
83 + 8726573 = 8726656
149 + 8726507 = 8726656
293 + 8726363 = 8726656
383 + 8726273 = 8726656
563 + 8726093 = 8726656
569 + 8726087 = 8726656
593 + 8726063 = 8726656

Showing the first eight; more decompositions exist.
