Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13690, here are decompositions:

3 + 13687 = 13690
11 + 13679 = 13690
41 + 13649 = 13690
71 + 13619 = 13690
113 + 13577 = 13690
137 + 13553 = 13690
167 + 13523 = 13690
191 + 13499 = 13690

Showing the first eight; more decompositions exist.
