Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641498, here are decompositions:

29 + 8641469 = 8641498
137 + 8641361 = 8641498
149 + 8641349 = 8641498
167 + 8641331 = 8641498
179 + 8641319 = 8641498
197 + 8641301 = 8641498
251 + 8641247 = 8641498
311 + 8641187 = 8641498

Showing the first eight; more decompositions exist.
