Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13538, here are decompositions:

61 + 13477 = 13538
97 + 13441 = 13538
127 + 13411 = 13538
139 + 13399 = 13538
157 + 13381 = 13538
199 + 13339 = 13538
211 + 13327 = 13538
229 + 13309 = 13538

Showing the first eight; more decompositions exist.
