Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749564, here are decompositions:

107 + 8749457 = 8749564
113 + 8749451 = 8749564
227 + 8749337 = 8749564
233 + 8749331 = 8749564
401 + 8749163 = 8749564
431 + 8749133 = 8749564
443 + 8749121 = 8749564
557 + 8749007 = 8749564

Showing the first eight; more decompositions exist.
