Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749880, here are decompositions:

43 + 8749837 = 8749880
67 + 8749813 = 8749880
109 + 8749771 = 8749880
127 + 8749753 = 8749880
211 + 8749669 = 8749880
229 + 8749651 = 8749880
277 + 8749603 = 8749880
331 + 8749549 = 8749880

Showing the first eight; more decompositions exist.
