Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728364, here are decompositions:

61 + 8728303 = 8728364
103 + 8728261 = 8728364
157 + 8728207 = 8728364
433 + 8727931 = 8728364
457 + 8727907 = 8728364
607 + 8727757 = 8728364
691 + 8727673 = 8728364
787 + 8727577 = 8728364

Showing the first eight; more decompositions exist.
