Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979390, here are decompositions:

11 + 979379 = 979390
17 + 979373 = 979390
29 + 979361 = 979390
47 + 979343 = 979390
53 + 979337 = 979390
107 + 979283 = 979390
179 + 979211 = 979390
227 + 979163 = 979390

Showing the first eight; more decompositions exist.
