Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72826, here are decompositions:

3 + 72823 = 72826
29 + 72797 = 72826
59 + 72767 = 72826
107 + 72719 = 72826
137 + 72689 = 72826
179 + 72647 = 72826
293 + 72533 = 72826
359 + 72467 = 72826

Showing the first eight; more decompositions exist.
