Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645906, here are decompositions:

7 + 8645899 = 8645906
19 + 8645887 = 8645906
43 + 8645863 = 8645906
103 + 8645803 = 8645906
457 + 8645449 = 8645906
463 + 8645443 = 8645906
499 + 8645407 = 8645906
547 + 8645359 = 8645906

Showing the first eight; more decompositions exist.
