Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728846, here are decompositions:

23 + 8728823 = 8728846
59 + 8728787 = 8728846
89 + 8728757 = 8728846
167 + 8728679 = 8728846
197 + 8728649 = 8728846
239 + 8728607 = 8728846
389 + 8728457 = 8728846
419 + 8728427 = 8728846

Showing the first eight; more decompositions exist.
