Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630620, here are decompositions:

29 + 8630591 = 8630620
101 + 8630519 = 8630620
137 + 8630483 = 8630620
233 + 8630387 = 8630620
389 + 8630231 = 8630620
419 + 8630201 = 8630620
443 + 8630177 = 8630620
461 + 8630159 = 8630620

Showing the first eight; more decompositions exist.
