Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749874, here are decompositions:

37 + 8749837 = 8749874
61 + 8749813 = 8749874
103 + 8749771 = 8749874
223 + 8749651 = 8749874
271 + 8749603 = 8749874
457 + 8749417 = 8749874
631 + 8749243 = 8749874
733 + 8749141 = 8749874

Showing the first eight; more decompositions exist.
