Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670384, here are decompositions:

11 + 8670373 = 8670384
13 + 8670371 = 8670384
31 + 8670353 = 8670384
53 + 8670331 = 8670384
71 + 8670313 = 8670384
83 + 8670301 = 8670384
103 + 8670281 = 8670384
127 + 8670257 = 8670384

Showing the first eight; more decompositions exist.
