Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673280, here are decompositions:

59 + 8673221 = 8673280
71 + 8673209 = 8673280
113 + 8673167 = 8673280
149 + 8673131 = 8673280
167 + 8673113 = 8673280
173 + 8673107 = 8673280
251 + 8673029 = 8673280
269 + 8673011 = 8673280

Showing the first eight; more decompositions exist.
