Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727894, here are decompositions:

23 + 8727871 = 8727894
37 + 8727857 = 8727894
103 + 8727791 = 8727894
127 + 8727767 = 8727894
137 + 8727757 = 8727894
163 + 8727731 = 8727894
167 + 8727727 = 8727894
193 + 8727701 = 8727894

Showing the first eight; more decompositions exist.
