Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735218, here are decompositions:

179 + 8735039 = 8735218
449 + 8734769 = 8735218
461 + 8734757 = 8735218
521 + 8734697 = 8735218
641 + 8734577 = 8735218
647 + 8734571 = 8735218
797 + 8734421 = 8735218
857 + 8734361 = 8735218

Showing the first eight; more decompositions exist.
