Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660426, here are decompositions:

3 + 8660423 = 8660426
7 + 8660419 = 8660426
13 + 8660413 = 8660426
43 + 8660383 = 8660426
139 + 8660287 = 8660426
157 + 8660269 = 8660426
163 + 8660263 = 8660426
193 + 8660233 = 8660426

Showing the first eight; more decompositions exist.
