Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978668, here are decompositions:

127 + 978541 = 978668
157 + 978511 = 978668
211 + 978457 = 978668
241 + 978427 = 978668
331 + 978337 = 978668
487 + 978181 = 978668
577 + 978091 = 978668
601 + 978067 = 978668

Showing the first eight; more decompositions exist.
