Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675240, here are decompositions:

19 + 8675221 = 8675240
43 + 8675197 = 8675240
103 + 8675137 = 8675240
127 + 8675113 = 8675240
181 + 8675059 = 8675240
193 + 8675047 = 8675240
229 + 8675011 = 8675240
313 + 8674927 = 8675240

Showing the first eight; more decompositions exist.
