Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749826, here are decompositions:

13 + 8749813 = 8749826
37 + 8749789 = 8749826
73 + 8749753 = 8749826
157 + 8749669 = 8749826
199 + 8749627 = 8749826
223 + 8749603 = 8749826
277 + 8749549 = 8749826
409 + 8749417 = 8749826

Showing the first eight; more decompositions exist.
