Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622712, here are decompositions:

5 + 8622707 = 8622712
29 + 8622683 = 8622712
101 + 8622611 = 8622712
149 + 8622563 = 8622712
191 + 8622521 = 8622712
239 + 8622473 = 8622712
251 + 8622461 = 8622712
353 + 8622359 = 8622712

Showing the first eight; more decompositions exist.
