Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642758, here are decompositions:

11 + 8642747 = 8642758
107 + 8642651 = 8642758
167 + 8642591 = 8642758
191 + 8642567 = 8642758
239 + 8642519 = 8642758
251 + 8642507 = 8642758
269 + 8642489 = 8642758
521 + 8642237 = 8642758

Showing the first eight; more decompositions exist.
