Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728196, here are decompositions:

3 + 8728193 = 8728196
67 + 8728129 = 8728196
283 + 8727913 = 8728196
439 + 8727757 = 8728196
523 + 8727673 = 8728196
577 + 8727619 = 8728196
613 + 8727583 = 8728196
619 + 8727577 = 8728196

Showing the first eight; more decompositions exist.
