Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745126, here are decompositions:

7 + 8745119 = 8745126
29 + 8745097 = 8745126
59 + 8745067 = 8745126
107 + 8745019 = 8745126
109 + 8745017 = 8745126
157 + 8744969 = 8745126
197 + 8744929 = 8745126
199 + 8744927 = 8745126

Showing the first eight; more decompositions exist.
