Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732856, here are decompositions:

17 + 8732839 = 8732856
23 + 8732833 = 8732856
37 + 8732819 = 8732856
59 + 8732797 = 8732856
107 + 8732749 = 8732856
113 + 8732743 = 8732856
137 + 8732719 = 8732856
179 + 8732677 = 8732856

Showing the first eight; more decompositions exist.
