Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979218, here are decompositions:

7 + 979211 = 979218
11 + 979207 = 979218
17 + 979201 = 979218
29 + 979189 = 979218
41 + 979177 = 979218
47 + 979171 = 979218
59 + 979159 = 979218
101 + 979117 = 979218

Showing the first eight; more decompositions exist.
