Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749480, here are decompositions:

11 + 8749469 = 8749480
23 + 8749457 = 8749480
29 + 8749451 = 8749480
41 + 8749439 = 8749480
59 + 8749421 = 8749480
137 + 8749343 = 8749480
149 + 8749331 = 8749480
251 + 8749229 = 8749480

Showing the first eight; more decompositions exist.
