Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72730, here are decompositions:

3 + 72727 = 72730
11 + 72719 = 72730
23 + 72707 = 72730
29 + 72701 = 72730
41 + 72689 = 72730
59 + 72671 = 72730
83 + 72647 = 72730
107 + 72623 = 72730

Showing the first eight; more decompositions exist.
