Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631166, here are decompositions:

83 + 8631083 = 8631166
149 + 8631017 = 8631166
263 + 8630903 = 8631166
353 + 8630813 = 8631166
503 + 8630663 = 8631166
647 + 8630519 = 8631166
683 + 8630483 = 8631166
1049 + 8630117 = 8631166

Showing the first eight; more decompositions exist.
