Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640356, here are decompositions:

7 + 8640349 = 8640356
19 + 8640337 = 8640356
97 + 8640259 = 8640356
223 + 8640133 = 8640356
379 + 8639977 = 8640356
433 + 8639923 = 8640356
457 + 8639899 = 8640356
547 + 8639809 = 8640356

Showing the first eight; more decompositions exist.
