Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656412, here are decompositions:

13 + 8656399 = 8656412
19 + 8656393 = 8656412
43 + 8656369 = 8656412
73 + 8656339 = 8656412
139 + 8656273 = 8656412
181 + 8656231 = 8656412
223 + 8656189 = 8656412
241 + 8656171 = 8656412

Showing the first eight; more decompositions exist.
