Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745258, here are decompositions:

17 + 8745241 = 8745258
19 + 8745239 = 8745258
31 + 8745227 = 8745258
59 + 8745199 = 8745258
89 + 8745169 = 8745258
97 + 8745161 = 8745258
139 + 8745119 = 8745258
157 + 8745101 = 8745258

Showing the first eight; more decompositions exist.
