Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728526, here are decompositions:

13 + 8728513 = 8728526
43 + 8728483 = 8728526
139 + 8728387 = 8728526
223 + 8728303 = 8728526
379 + 8728147 = 8728526
397 + 8728129 = 8728526
613 + 8727913 = 8728526
619 + 8727907 = 8728526

Showing the first eight; more decompositions exist.
