Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978210, here are decompositions:

7 + 978203 = 978210
29 + 978181 = 978210
31 + 978179 = 978210
53 + 978157 = 978210
59 + 978151 = 978210
61 + 978149 = 978210
97 + 978113 = 978210
131 + 978079 = 978210

Showing the first eight; more decompositions exist.
