Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978586, here are decompositions:

17 + 978569 = 978586
107 + 978479 = 978586
113 + 978473 = 978586
137 + 978449 = 978586
173 + 978413 = 978586
197 + 978389 = 978586
227 + 978359 = 978586
239 + 978347 = 978586

Showing the first eight; more decompositions exist.
