Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631566, here are decompositions:

67 + 8631499 = 8631566
193 + 8631373 = 8631566
199 + 8631367 = 8631566
283 + 8631283 = 8631566
337 + 8631229 = 8631566
367 + 8631199 = 8631566
373 + 8631193 = 8631566
457 + 8631109 = 8631566

Showing the first eight; more decompositions exist.
