Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745450, here are decompositions:

13 + 8745437 = 8745450
31 + 8745419 = 8745450
83 + 8745367 = 8745450
97 + 8745353 = 8745450
107 + 8745343 = 8745450
139 + 8745311 = 8745450
151 + 8745299 = 8745450
211 + 8745239 = 8745450

Showing the first eight; more decompositions exist.
