Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636672, here are decompositions:

73 + 8636599 = 8636672
139 + 8636533 = 8636672
151 + 8636521 = 8636672
181 + 8636491 = 8636672
199 + 8636473 = 8636672
223 + 8636449 = 8636672
283 + 8636389 = 8636672
409 + 8636263 = 8636672

Showing the first eight; more decompositions exist.
