Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42736, here are decompositions:

17 + 42719 = 42736
47 + 42689 = 42736
53 + 42683 = 42736
59 + 42677 = 42736
167 + 42569 = 42736
179 + 42557 = 42736
227 + 42509 = 42736
263 + 42473 = 42736

Showing the first eight; more decompositions exist.
