Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13318, here are decompositions:

5 + 13313 = 13318
59 + 13259 = 13318
89 + 13229 = 13318
101 + 13217 = 13318
131 + 13187 = 13318
167 + 13151 = 13318
191 + 13127 = 13318
197 + 13121 = 13318

Showing the first eight; more decompositions exist.
