Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749588, here are decompositions:

17 + 8749571 = 8749588
131 + 8749457 = 8749588
137 + 8749451 = 8749588
149 + 8749439 = 8749588
167 + 8749421 = 8749588
251 + 8749337 = 8749588
257 + 8749331 = 8749588
359 + 8749229 = 8749588

Showing the first eight; more decompositions exist.
