Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978220, here are decompositions:

3 + 978217 = 978220
11 + 978209 = 978220
17 + 978203 = 978220
41 + 978179 = 978220
71 + 978149 = 978220
107 + 978113 = 978220
149 + 978071 = 978220
167 + 978053 = 978220

Showing the first eight; more decompositions exist.
