Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645582, here are decompositions:

3 + 8645579 = 8645582
139 + 8645443 = 8645582
151 + 8645431 = 8645582
223 + 8645359 = 8645582
229 + 8645353 = 8645582
241 + 8645341 = 8645582
313 + 8645269 = 8645582
571 + 8645011 = 8645582

Showing the first eight; more decompositions exist.
