Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978230, here are decompositions:

7 + 978223 = 978230
13 + 978217 = 978230
73 + 978157 = 978230
79 + 978151 = 978230
139 + 978091 = 978230
151 + 978079 = 978230
157 + 978073 = 978230
163 + 978067 = 978230

Showing the first eight; more decompositions exist.
