Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641322, here are decompositions:

3 + 8641319 = 8641322
13 + 8641309 = 8641322
73 + 8641249 = 8641322
229 + 8641093 = 8641322
373 + 8640949 = 8641322
433 + 8640889 = 8641322
439 + 8640883 = 8641322
463 + 8640859 = 8641322

Showing the first eight; more decompositions exist.
