Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631698, here are decompositions:

181 + 8631517 = 8631698
199 + 8631499 = 8631698
307 + 8631391 = 8631698
331 + 8631367 = 8631698
367 + 8631331 = 8631698
379 + 8631319 = 8631698
421 + 8631277 = 8631698
499 + 8631199 = 8631698

Showing the first eight; more decompositions exist.
