Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749486, here are decompositions:

17 + 8749469 = 8749486
29 + 8749457 = 8749486
47 + 8749439 = 8749486
149 + 8749337 = 8749486
257 + 8749229 = 8749486
353 + 8749133 = 8749486
359 + 8749127 = 8749486
467 + 8749019 = 8749486

Showing the first eight; more decompositions exist.
