Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978950, here are decompositions:

3 + 978947 = 978950
19 + 978931 = 978950
43 + 978907 = 978950
67 + 978883 = 978950
79 + 978871 = 978950
97 + 978853 = 978950
151 + 978799 = 978950
223 + 978727 = 978950

Showing the first eight; more decompositions exist.
