Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745420, here are decompositions:

53 + 8745367 = 8745420
67 + 8745353 = 8745420
109 + 8745311 = 8745420
113 + 8745307 = 8745420
179 + 8745241 = 8745420
181 + 8745239 = 8745420
193 + 8745227 = 8745420
197 + 8745223 = 8745420

Showing the first eight; more decompositions exist.
