Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640266, here are decompositions:

3 + 8640263 = 8640266
7 + 8640259 = 8640266
79 + 8640187 = 8640266
97 + 8640169 = 8640266
157 + 8640109 = 8640266
367 + 8639899 = 8640266
457 + 8639809 = 8640266
463 + 8639803 = 8640266

Showing the first eight; more decompositions exist.
