Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745672, here are decompositions:

59 + 8745613 = 8745672
101 + 8745571 = 8745672
149 + 8745523 = 8745672
179 + 8745493 = 8745672
223 + 8745449 = 8745672
373 + 8745299 = 8745672
431 + 8745241 = 8745672
433 + 8745239 = 8745672

Showing the first eight; more decompositions exist.
