Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625856, here are decompositions:

3 + 8625853 = 8625856
23 + 8625833 = 8625856
47 + 8625809 = 8625856
149 + 8625707 = 8625856
167 + 8625689 = 8625856
257 + 8625599 = 8625856
269 + 8625587 = 8625856
347 + 8625509 = 8625856

Showing the first eight; more decompositions exist.
