Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978682, here are decompositions:

71 + 978611 = 978682
83 + 978599 = 978682
113 + 978569 = 978682
191 + 978491 = 978682
233 + 978449 = 978682
269 + 978413 = 978682
293 + 978389 = 978682
359 + 978323 = 978682

Showing the first eight; more decompositions exist.
