Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979778, here are decompositions:

31 + 979747 = 979778
61 + 979717 = 979778
127 + 979651 = 979778
211 + 979567 = 979778
229 + 979549 = 979778
307 + 979471 = 979778
409 + 979369 = 979778
487 + 979291 = 979778

Showing the first eight; more decompositions exist.
