Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641606, here are decompositions:

3 + 8641603 = 8641606
59 + 8641547 = 8641606
89 + 8641517 = 8641606
137 + 8641469 = 8641606
173 + 8641433 = 8641606
257 + 8641349 = 8641606
317 + 8641289 = 8641606
359 + 8641247 = 8641606

Showing the first eight; more decompositions exist.
