Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67540, here are decompositions:

3 + 67537 = 67540
17 + 67523 = 67540
29 + 67511 = 67540
41 + 67499 = 67540
47 + 67493 = 67540
59 + 67481 = 67540
107 + 67433 = 67540
113 + 67427 = 67540

Showing the first eight; more decompositions exist.
