Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672666, here are decompositions:

7 + 8672659 = 8672666
19 + 8672647 = 8672666
103 + 8672563 = 8672666
127 + 8672539 = 8672666
139 + 8672527 = 8672666
157 + 8672509 = 8672666
313 + 8672353 = 8672666
463 + 8672203 = 8672666

Showing the first eight; more decompositions exist.
