Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673666, here are decompositions:

73 + 8673593 = 8673666
97 + 8673569 = 8673666
149 + 8673517 = 8673666
167 + 8673499 = 8673666
233 + 8673433 = 8673666
277 + 8673389 = 8673666
293 + 8673373 = 8673666
307 + 8673359 = 8673666

Showing the first eight; more decompositions exist.
