Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728116, here are decompositions:

37 + 8728079 = 8728116
43 + 8728073 = 8728116
79 + 8728037 = 8728116
127 + 8727989 = 8728116
179 + 8727937 = 8728116
307 + 8727809 = 8728116
337 + 8727779 = 8728116
349 + 8727767 = 8728116

Showing the first eight; more decompositions exist.
