Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673864, here are decompositions:

47 + 8673817 = 8673864
83 + 8673781 = 8673864
103 + 8673761 = 8673864
137 + 8673727 = 8673864
181 + 8673683 = 8673864
263 + 8673601 = 8673864
271 + 8673593 = 8673864
293 + 8673571 = 8673864

Showing the first eight; more decompositions exist.
