Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749512, here are decompositions:

43 + 8749469 = 8749512
61 + 8749451 = 8749512
73 + 8749439 = 8749512
89 + 8749423 = 8749512
181 + 8749331 = 8749512
269 + 8749243 = 8749512
283 + 8749229 = 8749512
293 + 8749219 = 8749512

Showing the first eight; more decompositions exist.
