Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745142, here are decompositions:

23 + 8745119 = 8745142
41 + 8745101 = 8745142
71 + 8745071 = 8745142
173 + 8744969 = 8745142
191 + 8744951 = 8745142
233 + 8744909 = 8745142
239 + 8744903 = 8745142
251 + 8744891 = 8745142

Showing the first eight; more decompositions exist.
