Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72814, here are decompositions:

17 + 72797 = 72814
47 + 72767 = 72814
107 + 72707 = 72814
113 + 72701 = 72814
167 + 72647 = 72814
191 + 72623 = 72814
197 + 72617 = 72814
263 + 72551 = 72814

Showing the first eight; more decompositions exist.
