Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641546, here are decompositions:

3 + 8641543 = 8641546
5 + 8641541 = 8641546
29 + 8641517 = 8641546
113 + 8641433 = 8641546
197 + 8641349 = 8641546
227 + 8641319 = 8641546
257 + 8641289 = 8641546
359 + 8641187 = 8641546

Showing the first eight; more decompositions exist.
