Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660650, here are decompositions:

41 + 8660609 = 8660650
71 + 8660579 = 8660650
107 + 8660543 = 8660650
113 + 8660537 = 8660650
227 + 8660423 = 8660650
263 + 8660387 = 8660650
269 + 8660381 = 8660650
281 + 8660369 = 8660650

Showing the first eight; more decompositions exist.
