Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726518, here are decompositions:

11 + 8726507 = 8726518
71 + 8726447 = 8726518
137 + 8726381 = 8726518
167 + 8726351 = 8726518
431 + 8726087 = 8726518
467 + 8726051 = 8726518
491 + 8726027 = 8726518
557 + 8725961 = 8726518

Showing the first eight; more decompositions exist.
