Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979490, here are decompositions:

19 + 979471 = 979490
67 + 979423 = 979490
157 + 979333 = 979490
163 + 979327 = 979490
199 + 979291 = 979490
229 + 979261 = 979490
271 + 979219 = 979490
283 + 979207 = 979490

Showing the first eight; more decompositions exist.
