Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734728, here are decompositions:

31 + 8734697 = 8734728
89 + 8734639 = 8734728
151 + 8734577 = 8734728
157 + 8734571 = 8734728
227 + 8734501 = 8734728
307 + 8734421 = 8734728
311 + 8734417 = 8734728
367 + 8734361 = 8734728

Showing the first eight; more decompositions exist.
