Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717230, here are decompositions:

17 + 8717213 = 8717230
29 + 8717201 = 8717230
59 + 8717171 = 8717230
107 + 8717123 = 8717230
113 + 8717117 = 8717230
233 + 8716997 = 8717230
311 + 8716919 = 8717230
461 + 8716769 = 8717230

Showing the first eight; more decompositions exist.
