Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978680, here are decompositions:

37 + 978643 = 978680
61 + 978619 = 978680
139 + 978541 = 978680
223 + 978457 = 978680
277 + 978403 = 978680
331 + 978349 = 978680
337 + 978343 = 978680
397 + 978283 = 978680

Showing the first eight; more decompositions exist.
