Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726788, here are decompositions:

11 + 8726777 = 8726788
29 + 8726759 = 8726788
89 + 8726699 = 8726788
101 + 8726687 = 8726788
281 + 8726507 = 8726788
431 + 8726357 = 8726788
647 + 8726141 = 8726788
701 + 8726087 = 8726788

Showing the first eight; more decompositions exist.
