Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13642, here are decompositions:

23 + 13619 = 13642
29 + 13613 = 13642
89 + 13553 = 13642
173 + 13469 = 13642
179 + 13463 = 13642
191 + 13451 = 13642
311 + 13331 = 13642
383 + 13259 = 13642

Showing the first eight; more decompositions exist.
