Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641426, here are decompositions:

5 + 8641421 = 8641426
107 + 8641319 = 8641426
137 + 8641289 = 8641426
179 + 8641247 = 8641426
239 + 8641187 = 8641426
293 + 8641133 = 8641426
347 + 8641079 = 8641426
419 + 8641007 = 8641426

Showing the first eight; more decompositions exist.
