Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979886, here are decompositions:

3 + 979883 = 979886
13 + 979873 = 979886
67 + 979819 = 979886
79 + 979807 = 979886
139 + 979747 = 979886
337 + 979549 = 979886
367 + 979519 = 979886
463 + 979423 = 979886

Showing the first eight; more decompositions exist.
