Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978684, here are decompositions:

37 + 978647 = 978684
41 + 978643 = 978684
67 + 978617 = 978684
73 + 978611 = 978684
163 + 978521 = 978684
173 + 978511 = 978684
193 + 978491 = 978684
211 + 978473 = 978684

Showing the first eight; more decompositions exist.
