Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655904, here are decompositions:

3 + 8655901 = 8655904
197 + 8655707 = 8655904
227 + 8655677 = 8655904
233 + 8655671 = 8655904
251 + 8655653 = 8655904
263 + 8655641 = 8655904
281 + 8655623 = 8655904
293 + 8655611 = 8655904

Showing the first eight; more decompositions exist.
