Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979428, here are decompositions:

5 + 979423 = 979428
59 + 979369 = 979428
67 + 979361 = 979428
101 + 979327 = 979428
137 + 979291 = 979428
167 + 979261 = 979428
199 + 979229 = 979428
227 + 979201 = 979428

Showing the first eight; more decompositions exist.
