Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645406, here are decompositions:

47 + 8645359 = 8645406
53 + 8645353 = 8645406
79 + 8645327 = 8645406
113 + 8645293 = 8645406
137 + 8645269 = 8645406
139 + 8645267 = 8645406
149 + 8645257 = 8645406
163 + 8645243 = 8645406

Showing the first eight; more decompositions exist.
