Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645588, here are decompositions:

97 + 8645491 = 8645588
139 + 8645449 = 8645588
157 + 8645431 = 8645588
181 + 8645407 = 8645588
229 + 8645359 = 8645588
307 + 8645281 = 8645588
331 + 8645257 = 8645588
349 + 8645239 = 8645588

Showing the first eight; more decompositions exist.
