Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645606, here are decompositions:

19 + 8645587 = 8645606
157 + 8645449 = 8645606
163 + 8645443 = 8645606
199 + 8645407 = 8645606
313 + 8645293 = 8645606
337 + 8645269 = 8645606
349 + 8645257 = 8645606
367 + 8645239 = 8645606

Showing the first eight; more decompositions exist.
