Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008660, here are decompositions:

43 + 1008617 = 1008660
47 + 1008613 = 1008660
53 + 1008607 = 1008660
71 + 1008589 = 1008660
73 + 1008587 = 1008660
89 + 1008571 = 1008660
97 + 1008563 = 1008660
113 + 1008547 = 1008660

Showing the first eight; more decompositions exist.
