Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979930, here are decompositions:

11 + 979919 = 979930
23 + 979907 = 979930
41 + 979889 = 979930
47 + 979883 = 979930
173 + 979757 = 979930
239 + 979691 = 979930
389 + 979541 = 979930
401 + 979529 = 979930

Showing the first eight; more decompositions exist.
