Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745402, here are decompositions:

59 + 8745343 = 8745402
73 + 8745329 = 8745402
103 + 8745299 = 8745402
163 + 8745239 = 8745402
179 + 8745223 = 8745402
199 + 8745203 = 8745402
233 + 8745169 = 8745402
241 + 8745161 = 8745402

Showing the first eight; more decompositions exist.
