Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749510, here are decompositions:

41 + 8749469 = 8749510
53 + 8749457 = 8749510
59 + 8749451 = 8749510
71 + 8749439 = 8749510
89 + 8749421 = 8749510
167 + 8749343 = 8749510
173 + 8749337 = 8749510
179 + 8749331 = 8749510

Showing the first eight; more decompositions exist.
