Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979478, here are decompositions:

7 + 979471 = 979478
109 + 979369 = 979478
151 + 979327 = 979478
271 + 979207 = 979478
277 + 979201 = 979478
307 + 979171 = 979478
547 + 978931 = 979478
571 + 978907 = 979478

Showing the first eight; more decompositions exist.
