Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645346, here are decompositions:

5 + 8645341 = 8645346
19 + 8645327 = 8645346
53 + 8645293 = 8645346
79 + 8645267 = 8645346
89 + 8645257 = 8645346
103 + 8645243 = 8645346
107 + 8645239 = 8645346
109 + 8645237 = 8645346

Showing the first eight; more decompositions exist.
