Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708240, here are decompositions:

43 + 8708197 = 8708240
67 + 8708173 = 8708240
97 + 8708143 = 8708240
139 + 8708101 = 8708240
223 + 8708017 = 8708240
241 + 8707999 = 8708240
271 + 8707969 = 8708240
337 + 8707903 = 8708240

Showing the first eight; more decompositions exist.
