Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631562, here are decompositions:

29 + 8631533 = 8631562
83 + 8631479 = 8631562
293 + 8631269 = 8631562
311 + 8631251 = 8631562
479 + 8631083 = 8631562
521 + 8631041 = 8631562
659 + 8630903 = 8631562
701 + 8630861 = 8631562

Showing the first eight; more decompositions exist.
