Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678650, here are decompositions:

11 + 8678639 = 8678650
47 + 8678603 = 8678650
131 + 8678519 = 8678650
251 + 8678399 = 8678650
257 + 8678393 = 8678650
311 + 8678339 = 8678650
317 + 8678333 = 8678650
503 + 8678147 = 8678650

Showing the first eight; more decompositions exist.
