Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000660, here are decompositions:

41 + 1000619 = 1000660
71 + 1000589 = 1000660
83 + 1000577 = 1000660
113 + 1000547 = 1000660
233 + 1000427 = 1000660
251 + 1000409 = 1000660
257 + 1000403 = 1000660
263 + 1000397 = 1000660

Showing the first eight; more decompositions exist.
