Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749810, here are decompositions:

23 + 8749787 = 8749810
59 + 8749751 = 8749810
197 + 8749613 = 8749810
239 + 8749571 = 8749810
353 + 8749457 = 8749810
359 + 8749451 = 8749810
389 + 8749421 = 8749810
467 + 8749343 = 8749810

Showing the first eight; more decompositions exist.
