Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728050, here are decompositions:

13 + 8728037 = 8728050
61 + 8727989 = 8728050
113 + 8727937 = 8728050
137 + 8727913 = 8728050
151 + 8727899 = 8728050
179 + 8727871 = 8728050
193 + 8727857 = 8728050
241 + 8727809 = 8728050

Showing the first eight; more decompositions exist.
