Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642676, here are decompositions:

43 + 8642633 = 8642676
109 + 8642567 = 8642676
157 + 8642519 = 8642676
167 + 8642509 = 8642676
223 + 8642453 = 8642676
227 + 8642449 = 8642676
293 + 8642383 = 8642676
347 + 8642329 = 8642676

Showing the first eight; more decompositions exist.
