Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672668, here are decompositions:

29 + 8672639 = 8672668
47 + 8672621 = 8672668
71 + 8672597 = 8672668
107 + 8672561 = 8672668
149 + 8672519 = 8672668
167 + 8672501 = 8672668
197 + 8672471 = 8672668
227 + 8672441 = 8672668

Showing the first eight; more decompositions exist.
