Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726328, here are decompositions:

5 + 8726323 = 8726328
71 + 8726257 = 8726328
89 + 8726239 = 8726328
101 + 8726227 = 8726328
131 + 8726197 = 8726328
227 + 8726101 = 8726328
241 + 8726087 = 8726328
277 + 8726051 = 8726328

Showing the first eight; more decompositions exist.
