Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647412, here are decompositions:

3 + 8647409 = 8647412
19 + 8647393 = 8647412
43 + 8647369 = 8647412
139 + 8647273 = 8647412
181 + 8647231 = 8647412
229 + 8647183 = 8647412
283 + 8647129 = 8647412
349 + 8647063 = 8647412

Showing the first eight; more decompositions exist.
