Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656406, here are decompositions:

7 + 8656399 = 8656406
13 + 8656393 = 8656406
37 + 8656369 = 8656406
43 + 8656363 = 8656406
67 + 8656339 = 8656406
127 + 8656279 = 8656406
229 + 8656177 = 8656406
277 + 8656129 = 8656406

Showing the first eight; more decompositions exist.
