Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978310, here are decompositions:

23 + 978287 = 978310
41 + 978269 = 978310
71 + 978239 = 978310
101 + 978209 = 978310
107 + 978203 = 978310
131 + 978179 = 978310
197 + 978113 = 978310
233 + 978077 = 978310

Showing the first eight; more decompositions exist.
