Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728106, here are decompositions:

193 + 8727913 = 8728106
199 + 8727907 = 8728106
349 + 8727757 = 8728106
379 + 8727727 = 8728106
433 + 8727673 = 8728106
463 + 8727643 = 8728106
487 + 8727619 = 8728106
523 + 8727583 = 8728106

Showing the first eight; more decompositions exist.
