Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630966, here are decompositions:

37 + 8630929 = 8630966
67 + 8630899 = 8630966
109 + 8630857 = 8630966
229 + 8630737 = 8630966
283 + 8630683 = 8630966
313 + 8630653 = 8630966
367 + 8630599 = 8630966
373 + 8630593 = 8630966

Showing the first eight; more decompositions exist.
