Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708210, here are decompositions:

13 + 8708197 = 8708210
37 + 8708173 = 8708210
67 + 8708143 = 8708210
109 + 8708101 = 8708210
139 + 8708071 = 8708210
193 + 8708017 = 8708210
211 + 8707999 = 8708210
241 + 8707969 = 8708210

Showing the first eight; more decompositions exist.
