Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72726, here are decompositions:

7 + 72719 = 72726
19 + 72707 = 72726
37 + 72689 = 72726
47 + 72679 = 72726
53 + 72673 = 72726
79 + 72647 = 72726
83 + 72643 = 72726
103 + 72623 = 72726

Showing the first eight; more decompositions exist.
