Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671604, here are decompositions:

31 + 8671573 = 8671604
103 + 8671501 = 8671604
157 + 8671447 = 8671604
163 + 8671441 = 8671604
211 + 8671393 = 8671604
223 + 8671381 = 8671604
241 + 8671363 = 8671604
283 + 8671321 = 8671604

Showing the first eight; more decompositions exist.
