Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641486, here are decompositions:

17 + 8641469 = 8641486
53 + 8641433 = 8641486
137 + 8641349 = 8641486
167 + 8641319 = 8641486
197 + 8641289 = 8641486
239 + 8641247 = 8641486
353 + 8641133 = 8641486
389 + 8641097 = 8641486

Showing the first eight; more decompositions exist.
