Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670512, here are decompositions:

3 + 8670509 = 8670512
13 + 8670499 = 8670512
31 + 8670481 = 8670512
61 + 8670451 = 8670512
79 + 8670433 = 8670512
139 + 8670373 = 8670512
181 + 8670331 = 8670512
199 + 8670313 = 8670512

Showing the first eight; more decompositions exist.
