Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728022, here are decompositions:

109 + 8727913 = 8728022
151 + 8727871 = 8728022
349 + 8727673 = 8728022
379 + 8727643 = 8728022
421 + 8727601 = 8728022
439 + 8727583 = 8728022
571 + 8727451 = 8728022
673 + 8727349 = 8728022

Showing the first eight; more decompositions exist.
