Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978250, here are decompositions:

11 + 978239 = 978250
17 + 978233 = 978250
41 + 978209 = 978250
47 + 978203 = 978250
71 + 978179 = 978250
101 + 978149 = 978250
137 + 978113 = 978250
173 + 978077 = 978250

Showing the first eight; more decompositions exist.
