Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978650, here are decompositions:

3 + 978647 = 978650
7 + 978643 = 978650
31 + 978619 = 978650
109 + 978541 = 978650
139 + 978511 = 978650
193 + 978457 = 978650
223 + 978427 = 978650
307 + 978343 = 978650

Showing the first eight; more decompositions exist.
