Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672660, here are decompositions:

13 + 8672647 = 8672660
19 + 8672641 = 8672660
97 + 8672563 = 8672660
109 + 8672551 = 8672660
151 + 8672509 = 8672660
307 + 8672353 = 8672660
313 + 8672347 = 8672660
397 + 8672263 = 8672660

Showing the first eight; more decompositions exist.
