Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728044, here are decompositions:

7 + 8728037 = 8728044
107 + 8727937 = 8728044
113 + 8727931 = 8728044
131 + 8727913 = 8728044
137 + 8727907 = 8728044
173 + 8727871 = 8728044
271 + 8727773 = 8728044
277 + 8727767 = 8728044

Showing the first eight; more decompositions exist.
