Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018660, here are decompositions:

11 + 1018649 = 1018660
17 + 1018643 = 1018660
47 + 1018613 = 1018660
101 + 1018559 = 1018660
239 + 1018421 = 1018660
347 + 1018313 = 1018660
359 + 1018301 = 1018660
389 + 1018271 = 1018660

Showing the first eight; more decompositions exist.
