Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631554, here are decompositions:

37 + 8631517 = 8631554
103 + 8631451 = 8631554
163 + 8631391 = 8631554
181 + 8631373 = 8631554
223 + 8631331 = 8631554
271 + 8631283 = 8631554
277 + 8631277 = 8631554
307 + 8631247 = 8631554

Showing the first eight; more decompositions exist.
