Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728322, here are decompositions:

13 + 8728309 = 8728322
19 + 8728303 = 8728322
61 + 8728261 = 8728322
193 + 8728129 = 8728322
409 + 8727913 = 8728322
739 + 8727583 = 8728322
829 + 8727493 = 8728322
1039 + 8727283 = 8728322

Showing the first eight; more decompositions exist.
