Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13606, here are decompositions:

29 + 13577 = 13606
53 + 13553 = 13606
83 + 13523 = 13606
107 + 13499 = 13606
137 + 13469 = 13606
149 + 13457 = 13606
239 + 13367 = 13606
269 + 13337 = 13606

Showing the first eight; more decompositions exist.
