Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726286, here are decompositions:

13 + 8726273 = 8726286
29 + 8726257 = 8726286
43 + 8726243 = 8726286
47 + 8726239 = 8726286
59 + 8726227 = 8726286
83 + 8726203 = 8726286
89 + 8726197 = 8726286
193 + 8726093 = 8726286

Showing the first eight; more decompositions exist.
