Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745478, here are decompositions:

29 + 8745449 = 8745478
41 + 8745437 = 8745478
59 + 8745419 = 8745478
149 + 8745329 = 8745478
167 + 8745311 = 8745478
179 + 8745299 = 8745478
239 + 8745239 = 8745478
251 + 8745227 = 8745478

Showing the first eight; more decompositions exist.
