Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13512, here are decompositions:

13 + 13499 = 13512
43 + 13469 = 13512
61 + 13451 = 13512
71 + 13441 = 13512
101 + 13411 = 13512
113 + 13399 = 13512
131 + 13381 = 13512
173 + 13339 = 13512

Showing the first eight; more decompositions exist.
