Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749498, here are decompositions:

29 + 8749469 = 8749498
41 + 8749457 = 8749498
47 + 8749451 = 8749498
59 + 8749439 = 8749498
167 + 8749331 = 8749498
269 + 8749229 = 8749498
347 + 8749151 = 8749498
449 + 8749049 = 8749498

Showing the first eight; more decompositions exist.
