Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749646, here are decompositions:

19 + 8749627 = 8749646
43 + 8749603 = 8749646
67 + 8749579 = 8749646
97 + 8749549 = 8749646
223 + 8749423 = 8749646
229 + 8749417 = 8749646
337 + 8749309 = 8749646
439 + 8749207 = 8749646

Showing the first eight; more decompositions exist.
