Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726210, here are decompositions:

7 + 8726203 = 8726210
13 + 8726197 = 8726210
67 + 8726143 = 8726210
109 + 8726101 = 8726210
193 + 8726017 = 8726210
211 + 8725999 = 8726210
223 + 8725987 = 8726210
379 + 8725831 = 8726210

Showing the first eight; more decompositions exist.
