Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619550, here are decompositions:

11 + 8619539 = 8619550
41 + 8619509 = 8619550
59 + 8619491 = 8619550
89 + 8619461 = 8619550
113 + 8619437 = 8619550
197 + 8619353 = 8619550
281 + 8619269 = 8619550
353 + 8619197 = 8619550

Showing the first eight; more decompositions exist.
