Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624840, here are decompositions:

19 + 8624821 = 8624840
67 + 8624773 = 8624840
127 + 8624713 = 8624840
163 + 8624677 = 8624840
223 + 8624617 = 8624840
241 + 8624599 = 8624840
337 + 8624503 = 8624840
457 + 8624383 = 8624840

Showing the first eight; more decompositions exist.
