Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979128, here are decompositions:

11 + 979117 = 979128
19 + 979109 = 979128
67 + 979061 = 979128
97 + 979031 = 979128
127 + 979001 = 979128
131 + 978997 = 979128
181 + 978947 = 979128
197 + 978931 = 979128

Showing the first eight; more decompositions exist.
