Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728562, here are decompositions:

13 + 8728549 = 8728562
79 + 8728483 = 8728562
181 + 8728381 = 8728562
433 + 8728129 = 8728562
631 + 8727931 = 8728562
691 + 8727871 = 8728562
919 + 8727643 = 8728562
1033 + 8727529 = 8728562

Showing the first eight; more decompositions exist.
