Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13404, here are decompositions:

5 + 13399 = 13404
7 + 13397 = 13404
23 + 13381 = 13404
37 + 13367 = 13404
67 + 13337 = 13404
73 + 13331 = 13404
107 + 13297 = 13404
113 + 13291 = 13404

Showing the first eight; more decompositions exist.
