Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658318, here are decompositions:

5 + 8658313 = 8658318
29 + 8658289 = 8658318
41 + 8658277 = 8658318
101 + 8658217 = 8658318
157 + 8658161 = 8658318
181 + 8658137 = 8658318
211 + 8658107 = 8658318
349 + 8657969 = 8658318

Showing the first eight; more decompositions exist.
