Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622770, here are decompositions:

3 + 8622767 = 8622770
7 + 8622763 = 8622770
193 + 8622577 = 8622770
241 + 8622529 = 8622770
271 + 8622499 = 8622770
283 + 8622487 = 8622770
307 + 8622463 = 8622770
349 + 8622421 = 8622770

Showing the first eight; more decompositions exist.
