Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713210, here are decompositions:

17 + 8713193 = 8713210
29 + 8713181 = 8713210
53 + 8713157 = 8713210
83 + 8713127 = 8713210
89 + 8713121 = 8713210
101 + 8713109 = 8713210
167 + 8713043 = 8713210
173 + 8713037 = 8713210

Showing the first eight; more decompositions exist.
