Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978662, here are decompositions:

19 + 978643 = 978662
43 + 978619 = 978662
151 + 978511 = 978662
199 + 978463 = 978662
313 + 978349 = 978662
379 + 978283 = 978662
439 + 978223 = 978662
571 + 978091 = 978662

Showing the first eight; more decompositions exist.
