Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649856, here are decompositions:

3 + 8649853 = 8649856
53 + 8649803 = 8649856
167 + 8649689 = 8649856
179 + 8649677 = 8649856
227 + 8649629 = 8649856
233 + 8649623 = 8649856
389 + 8649467 = 8649856
503 + 8649353 = 8649856

Showing the first eight; more decompositions exist.
