Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649086, here are decompositions:

7 + 8649079 = 8649086
37 + 8649049 = 8649086
157 + 8648929 = 8649086
163 + 8648923 = 8649086
223 + 8648863 = 8649086
307 + 8648779 = 8649086
337 + 8648749 = 8649086
349 + 8648737 = 8649086

Showing the first eight; more decompositions exist.
