Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617238, here are decompositions:

31 + 8617207 = 8617238
37 + 8617201 = 8617238
61 + 8617177 = 8617238
67 + 8617171 = 8617238
109 + 8617129 = 8617238
241 + 8616997 = 8617238
337 + 8616901 = 8617238
379 + 8616859 = 8617238

Showing the first eight; more decompositions exist.
