Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670140, here are decompositions:

13 + 8670127 = 8670140
103 + 8670037 = 8670140
109 + 8670031 = 8670140
151 + 8669989 = 8670140
211 + 8669929 = 8670140
229 + 8669911 = 8670140
373 + 8669767 = 8670140
439 + 8669701 = 8670140

Showing the first eight; more decompositions exist.
