Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718230, here are decompositions:

13 + 8718217 = 8718230
67 + 8718163 = 8718230
127 + 8718103 = 8718230
139 + 8718091 = 8718230
223 + 8718007 = 8718230
271 + 8717959 = 8718230
349 + 8717881 = 8718230
373 + 8717857 = 8718230

Showing the first eight; more decompositions exist.
