Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745220, here are decompositions:

17 + 8745203 = 8745220
59 + 8745161 = 8745220
101 + 8745119 = 8745220
149 + 8745071 = 8745220
251 + 8744969 = 8745220
269 + 8744951 = 8745220
293 + 8744927 = 8745220
311 + 8744909 = 8745220

Showing the first eight; more decompositions exist.
