Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645366, here are decompositions:

7 + 8645359 = 8645366
13 + 8645353 = 8645366
73 + 8645293 = 8645366
97 + 8645269 = 8645366
109 + 8645257 = 8645366
127 + 8645239 = 8645366
313 + 8645053 = 8645366
337 + 8645029 = 8645366

Showing the first eight; more decompositions exist.
