Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672822, here are decompositions:

3 + 8672819 = 8672822
31 + 8672791 = 8672822
43 + 8672779 = 8672822
163 + 8672659 = 8672822
181 + 8672641 = 8672822
271 + 8672551 = 8672822
283 + 8672539 = 8672822
313 + 8672509 = 8672822

Showing the first eight; more decompositions exist.
