Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13630, here are decompositions:

3 + 13627 = 13630
11 + 13619 = 13630
17 + 13613 = 13630
53 + 13577 = 13630
107 + 13523 = 13630
131 + 13499 = 13630
167 + 13463 = 13630
173 + 13457 = 13630

Showing the first eight; more decompositions exist.
