Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728856, here are decompositions:

7 + 8728849 = 8728856
139 + 8728717 = 8728856
193 + 8728663 = 8728856
229 + 8728627 = 8728856
277 + 8728579 = 8728856
307 + 8728549 = 8728856
373 + 8728483 = 8728856
547 + 8728309 = 8728856

Showing the first eight; more decompositions exist.
