Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86672, here are decompositions:

43 + 86629 = 86672
73 + 86599 = 86672
139 + 86533 = 86672
163 + 86509 = 86672
181 + 86491 = 86672
211 + 86461 = 86672
283 + 86389 = 86672
331 + 86341 = 86672

Showing the first eight; more decompositions exist.
