Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671724, here are decompositions:

3 + 8671721 = 8671724
13 + 8671711 = 8671724
151 + 8671573 = 8671724
223 + 8671501 = 8671724
277 + 8671447 = 8671724
283 + 8671441 = 8671724
331 + 8671393 = 8671724
433 + 8671291 = 8671724

Showing the first eight; more decompositions exist.
