Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978730, here are decompositions:

3 + 978727 = 978730
17 + 978713 = 978730
41 + 978689 = 978730
47 + 978683 = 978730
83 + 978647 = 978730
113 + 978617 = 978730
131 + 978599 = 978730
239 + 978491 = 978730

Showing the first eight; more decompositions exist.
