Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718282, here are decompositions:

5 + 8718277 = 8718282
11 + 8718271 = 8718282
31 + 8718251 = 8718282
61 + 8718221 = 8718282
173 + 8718109 = 8718282
179 + 8718103 = 8718282
191 + 8718091 = 8718282
193 + 8718089 = 8718282

Showing the first eight; more decompositions exist.
