Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13570, here are decompositions:

3 + 13567 = 13570
17 + 13553 = 13570
47 + 13523 = 13570
71 + 13499 = 13570
83 + 13487 = 13570
101 + 13469 = 13570
107 + 13463 = 13570
113 + 13457 = 13570

Showing the first eight; more decompositions exist.
