Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728424, here are decompositions:

37 + 8728387 = 8728424
43 + 8728381 = 8728424
151 + 8728273 = 8728424
163 + 8728261 = 8728424
277 + 8728147 = 8728424
487 + 8727937 = 8728424
751 + 8727673 = 8728424
823 + 8727601 = 8728424

Showing the first eight; more decompositions exist.
