Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728226, here are decompositions:

19 + 8728207 = 8728226
79 + 8728147 = 8728226
97 + 8728129 = 8728226
313 + 8727913 = 8728226
499 + 8727727 = 8728226
607 + 8727619 = 8728226
643 + 8727583 = 8728226
733 + 8727493 = 8728226

Showing the first eight; more decompositions exist.
