Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672, here are decompositions:

3 + 8669 = 8672
31 + 8641 = 8672
43 + 8629 = 8672
73 + 8599 = 8672
109 + 8563 = 8672
151 + 8521 = 8672
211 + 8461 = 8672
229 + 8443 = 8672

Showing the first eight; more decompositions exist.
