Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645348, here are decompositions:

7 + 8645341 = 8645348
67 + 8645281 = 8645348
79 + 8645269 = 8645348
109 + 8645239 = 8645348
277 + 8645071 = 8645348
337 + 8645011 = 8645348
421 + 8644927 = 8645348
487 + 8644861 = 8645348

Showing the first eight; more decompositions exist.
