Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749662, here are decompositions:

11 + 8749651 = 8749662
59 + 8749603 = 8749662
73 + 8749589 = 8749662
83 + 8749579 = 8749662
113 + 8749549 = 8749662
193 + 8749469 = 8749662
211 + 8749451 = 8749662
223 + 8749439 = 8749662

Showing the first eight; more decompositions exist.
