Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670644, here are decompositions:

7 + 8670637 = 8670644
61 + 8670583 = 8670644
163 + 8670481 = 8670644
193 + 8670451 = 8670644
211 + 8670433 = 8670644
271 + 8670373 = 8670644
313 + 8670331 = 8670644
331 + 8670313 = 8670644

Showing the first eight; more decompositions exist.
