Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727942, here are decompositions:

5 + 8727937 = 8727942
11 + 8727931 = 8727942
29 + 8727913 = 8727942
43 + 8727899 = 8727942
71 + 8727871 = 8727942
151 + 8727791 = 8727942
163 + 8727779 = 8727942
211 + 8727731 = 8727942

Showing the first eight; more decompositions exist.
