Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645586, here are decompositions:

7 + 8645579 = 8645586
43 + 8645543 = 8645586
109 + 8645477 = 8645586
137 + 8645449 = 8645586
179 + 8645407 = 8645586
227 + 8645359 = 8645586
233 + 8645353 = 8645586
293 + 8645293 = 8645586

Showing the first eight; more decompositions exist.
