Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979220, here are decompositions:

13 + 979207 = 979220
19 + 979201 = 979220
31 + 979189 = 979220
43 + 979177 = 979220
61 + 979159 = 979220
103 + 979117 = 979220
127 + 979093 = 979220
157 + 979063 = 979220

Showing the first eight; more decompositions exist.
