Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979420, here are decompositions:

17 + 979403 = 979420
41 + 979379 = 979420
47 + 979373 = 979420
59 + 979361 = 979420
83 + 979337 = 979420
107 + 979313 = 979420
137 + 979283 = 979420
191 + 979229 = 979420

Showing the first eight; more decompositions exist.
