Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979280, here are decompositions:

7 + 979273 = 979280
19 + 979261 = 979280
61 + 979219 = 979280
73 + 979207 = 979280
79 + 979201 = 979280
103 + 979177 = 979280
109 + 979171 = 979280
163 + 979117 = 979280

Showing the first eight; more decompositions exist.
