Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630320, here are decompositions:

29 + 8630291 = 8630320
71 + 8630249 = 8630320
89 + 8630231 = 8630320
113 + 8630207 = 8630320
317 + 8630003 = 8630320
359 + 8629961 = 8630320
431 + 8629889 = 8630320
557 + 8629763 = 8630320

Showing the first eight; more decompositions exist.
