Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718284, here are decompositions:

7 + 8718277 = 8718284
13 + 8718271 = 8718284
37 + 8718247 = 8718284
67 + 8718217 = 8718284
181 + 8718103 = 8718284
193 + 8718091 = 8718284
241 + 8718043 = 8718284
271 + 8718013 = 8718284

Showing the first eight; more decompositions exist.
