Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72706, here are decompositions:

5 + 72701 = 72706
17 + 72689 = 72706
59 + 72647 = 72706
83 + 72623 = 72706
89 + 72617 = 72706
173 + 72533 = 72706
239 + 72467 = 72706
353 + 72353 = 72706

Showing the first eight; more decompositions exist.
