Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673320, here are decompositions:

163 + 8673157 = 8673320
193 + 8673127 = 8673320
199 + 8673121 = 8673320
211 + 8673109 = 8673320
223 + 8673097 = 8673320
283 + 8673037 = 8673320
367 + 8672953 = 8673320
373 + 8672947 = 8673320

Showing the first eight; more decompositions exist.
