Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631424, here are decompositions:

23 + 8631401 = 8631424
83 + 8631341 = 8631424
173 + 8631251 = 8631424
233 + 8631191 = 8631424
257 + 8631167 = 8631424
383 + 8631041 = 8631424
401 + 8631023 = 8631424
521 + 8630903 = 8631424

Showing the first eight; more decompositions exist.
