Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672864, here are decompositions:

3 + 8672861 = 8672864
43 + 8672821 = 8672864
73 + 8672791 = 8672864
97 + 8672767 = 8672864
157 + 8672707 = 8672864
223 + 8672641 = 8672864
313 + 8672551 = 8672864
337 + 8672527 = 8672864

Showing the first eight; more decompositions exist.
