Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641272, here are decompositions:

23 + 8641249 = 8641272
41 + 8641231 = 8641272
61 + 8641211 = 8641272
139 + 8641133 = 8641272
179 + 8641093 = 8641272
193 + 8641079 = 8641272
383 + 8640889 = 8641272
389 + 8640883 = 8641272

Showing the first eight; more decompositions exist.
