Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749804, here are decompositions:

17 + 8749787 = 8749804
53 + 8749751 = 8749804
71 + 8749733 = 8749804
191 + 8749613 = 8749804
197 + 8749607 = 8749804
233 + 8749571 = 8749804
347 + 8749457 = 8749804
353 + 8749451 = 8749804

Showing the first eight; more decompositions exist.
