Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646672, here are decompositions:

5 + 8646667 = 8646672
101 + 8646571 = 8646672
113 + 8646559 = 8646672
193 + 8646479 = 8646672
269 + 8646403 = 8646672
271 + 8646401 = 8646672
283 + 8646389 = 8646672
311 + 8646361 = 8646672

Showing the first eight; more decompositions exist.
