Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622726, here are decompositions:

5 + 8622721 = 8622726
19 + 8622707 = 8622726
43 + 8622683 = 8622726
149 + 8622577 = 8622726
163 + 8622563 = 8622726
197 + 8622529 = 8622726
227 + 8622499 = 8622726
239 + 8622487 = 8622726

Showing the first eight; more decompositions exist.
