Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745486, here are decompositions:

37 + 8745449 = 8745486
67 + 8745419 = 8745486
157 + 8745329 = 8745486
179 + 8745307 = 8745486
263 + 8745223 = 8745486
283 + 8745203 = 8745486
317 + 8745169 = 8745486
353 + 8745133 = 8745486

Showing the first eight; more decompositions exist.
