Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72736, here are decompositions:

3 + 72733 = 72736
17 + 72719 = 72736
29 + 72707 = 72736
47 + 72689 = 72736
89 + 72647 = 72736
113 + 72623 = 72736
233 + 72503 = 72736
239 + 72497 = 72736

Showing the first eight; more decompositions exist.
