Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13918, here are decompositions:

5 + 13913 = 13918
11 + 13907 = 13918
17 + 13901 = 13918
41 + 13877 = 13918
59 + 13859 = 13918
89 + 13829 = 13918
137 + 13781 = 13918
167 + 13751 = 13918

Showing the first eight; more decompositions exist.
