Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701138, here are decompositions:

71 + 8701067 = 8701138
137 + 8701001 = 8701138
191 + 8700947 = 8701138
197 + 8700941 = 8701138
227 + 8700911 = 8701138
269 + 8700869 = 8701138
311 + 8700827 = 8701138
557 + 8700581 = 8701138

Showing the first eight; more decompositions exist.
