Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726728, here are decompositions:

5 + 8726723 = 8726728
29 + 8726699 = 8726728
41 + 8726687 = 8726728
281 + 8726447 = 8726728
347 + 8726381 = 8726728
587 + 8726141 = 8726728
641 + 8726087 = 8726728
677 + 8726051 = 8726728

Showing the first eight; more decompositions exist.
