Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672918, here are decompositions:

97 + 8672821 = 8672918
127 + 8672791 = 8672918
139 + 8672779 = 8672918
151 + 8672767 = 8672918
211 + 8672707 = 8672918
271 + 8672647 = 8672918
277 + 8672641 = 8672918
367 + 8672551 = 8672918

Showing the first eight; more decompositions exist.
