Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745156, here are decompositions:

23 + 8745133 = 8745156
37 + 8745119 = 8745156
59 + 8745097 = 8745156
89 + 8745067 = 8745156
137 + 8745019 = 8745156
139 + 8745017 = 8745156
227 + 8744929 = 8745156
229 + 8744927 = 8745156

Showing the first eight; more decompositions exist.
