Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646562, here are decompositions:

3 + 8646559 = 8646562
59 + 8646503 = 8646562
83 + 8646479 = 8646562
173 + 8646389 = 8646562
233 + 8646329 = 8646562
263 + 8646299 = 8646562
269 + 8646293 = 8646562
293 + 8646269 = 8646562

Showing the first eight; more decompositions exist.
