Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749468, here are decompositions:

11 + 8749457 = 8749468
17 + 8749451 = 8749468
29 + 8749439 = 8749468
47 + 8749421 = 8749468
131 + 8749337 = 8749468
137 + 8749331 = 8749468
239 + 8749229 = 8749468
269 + 8749199 = 8749468

Showing the first eight; more decompositions exist.
