Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72718, here are decompositions:

11 + 72707 = 72718
17 + 72701 = 72718
29 + 72689 = 72718
47 + 72671 = 72718
71 + 72647 = 72718
101 + 72617 = 72718
167 + 72551 = 72718
251 + 72467 = 72718

Showing the first eight; more decompositions exist.
