Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739224, here are decompositions:

31 + 8739193 = 8739224
37 + 8739187 = 8739224
61 + 8739163 = 8739224
97 + 8739127 = 8739224
127 + 8739097 = 8739224
223 + 8739001 = 8739224
457 + 8738767 = 8739224
643 + 8738581 = 8739224

Showing the first eight; more decompositions exist.
