Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728026, here are decompositions:

37 + 8727989 = 8728026
89 + 8727937 = 8728026
113 + 8727913 = 8728026
127 + 8727899 = 8728026
269 + 8727757 = 8728026
337 + 8727689 = 8728026
353 + 8727673 = 8728026
367 + 8727659 = 8728026

Showing the first eight; more decompositions exist.
