Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979918, here are decompositions:

11 + 979907 = 979918
29 + 979889 = 979918
131 + 979787 = 979918
227 + 979691 = 979918
389 + 979529 = 979918
461 + 979457 = 979918
479 + 979439 = 979918
557 + 979361 = 979918

Showing the first eight; more decompositions exist.
