Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641676, here are decompositions:

3 + 8641673 = 8641676
7 + 8641669 = 8641676
73 + 8641603 = 8641676
157 + 8641519 = 8641676
163 + 8641513 = 8641676
223 + 8641453 = 8641676
349 + 8641327 = 8641676
367 + 8641309 = 8641676

Showing the first eight; more decompositions exist.
