Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8318, here are decompositions:

7 + 8311 = 8318
31 + 8287 = 8318
97 + 8221 = 8318
109 + 8209 = 8318
127 + 8191 = 8318
139 + 8179 = 8318
151 + 8167 = 8318
157 + 8161 = 8318

Showing the first eight; more decompositions exist.
