Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979838, here are decompositions:

7 + 979831 = 979838
19 + 979819 = 979838
31 + 979807 = 979838
271 + 979567 = 979838
367 + 979471 = 979838
547 + 979291 = 979838
577 + 979261 = 979838
619 + 979219 = 979838

Showing the first eight; more decompositions exist.
