Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13618, here are decompositions:

5 + 13613 = 13618
41 + 13577 = 13618
131 + 13487 = 13618
149 + 13469 = 13618
167 + 13451 = 13618
197 + 13421 = 13618
251 + 13367 = 13618
281 + 13337 = 13618

Showing the first eight; more decompositions exist.
