Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657856, here are decompositions:

5 + 8657851 = 8657856
7 + 8657849 = 8657856
23 + 8657833 = 8657856
29 + 8657827 = 8657856
73 + 8657783 = 8657856
89 + 8657767 = 8657856
157 + 8657699 = 8657856
223 + 8657633 = 8657856

Showing the first eight; more decompositions exist.
