Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81726, here are decompositions:

19 + 81707 = 81726
23 + 81703 = 81726
37 + 81689 = 81726
59 + 81667 = 81726
79 + 81647 = 81726
89 + 81637 = 81726
97 + 81629 = 81726
107 + 81619 = 81726

Showing the first eight; more decompositions exist.
