Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749684, here are decompositions:

71 + 8749613 = 8749684
113 + 8749571 = 8749684
227 + 8749457 = 8749684
233 + 8749451 = 8749684
263 + 8749421 = 8749684
347 + 8749337 = 8749684
353 + 8749331 = 8749684
521 + 8749163 = 8749684

Showing the first eight; more decompositions exist.
