Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978966, here are decompositions:

19 + 978947 = 978966
59 + 978907 = 978966
83 + 978883 = 978966
103 + 978863 = 978966
113 + 978853 = 978966
127 + 978839 = 978966
167 + 978799 = 978966
193 + 978773 = 978966

Showing the first eight; more decompositions exist.
