Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630980, here are decompositions:

167 + 8630813 = 8630980
191 + 8630789 = 8630980
311 + 8630669 = 8630980
317 + 8630663 = 8630980
389 + 8630591 = 8630980
461 + 8630519 = 8630980
503 + 8630477 = 8630980
563 + 8630417 = 8630980

Showing the first eight; more decompositions exist.
