Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606240, here are decompositions:

43 + 8606197 = 8606240
61 + 8606179 = 8606240
67 + 8606173 = 8606240
103 + 8606137 = 8606240
163 + 8606077 = 8606240
193 + 8606047 = 8606240
199 + 8606041 = 8606240
241 + 8605999 = 8606240

Showing the first eight; more decompositions exist.
