Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622686, here are decompositions:

3 + 8622683 = 8622686
109 + 8622577 = 8622686
157 + 8622529 = 8622686
199 + 8622487 = 8622686
223 + 8622463 = 8622686
307 + 8622379 = 8622686
313 + 8622373 = 8622686
349 + 8622337 = 8622686

Showing the first eight; more decompositions exist.
