Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726390, here are decompositions:

7 + 8726383 = 8726390
31 + 8726359 = 8726390
61 + 8726329 = 8726390
67 + 8726323 = 8726390
151 + 8726239 = 8726390
163 + 8726227 = 8726390
181 + 8726209 = 8726390
193 + 8726197 = 8726390

Showing the first eight; more decompositions exist.
