Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645262, here are decompositions:

5 + 8645257 = 8645262
19 + 8645243 = 8645262
23 + 8645239 = 8645262
83 + 8645179 = 8645262
139 + 8645123 = 8645262
149 + 8645113 = 8645262
181 + 8645081 = 8645262
191 + 8645071 = 8645262

Showing the first eight; more decompositions exist.
