Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13442, here are decompositions:

31 + 13411 = 13442
43 + 13399 = 13442
61 + 13381 = 13442
103 + 13339 = 13442
151 + 13291 = 13442
193 + 13249 = 13442
223 + 13219 = 13442
271 + 13171 = 13442

Showing the first eight; more decompositions exist.
