Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734840, here are decompositions:

17 + 8734823 = 8734840
71 + 8734769 = 8734840
83 + 8734757 = 8734840
197 + 8734643 = 8734840
227 + 8734613 = 8734840
263 + 8734577 = 8734840
269 + 8734571 = 8734840
419 + 8734421 = 8734840

Showing the first eight; more decompositions exist.
