Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726650, here are decompositions:

3 + 8726647 = 8726650
17 + 8726633 = 8726650
269 + 8726381 = 8726650
293 + 8726357 = 8726650
509 + 8726141 = 8726650
557 + 8726093 = 8726650
563 + 8726087 = 8726650
587 + 8726063 = 8726650

Showing the first eight; more decompositions exist.
