Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72856, here are decompositions:

59 + 72797 = 72856
89 + 72767 = 72856
137 + 72719 = 72856
149 + 72707 = 72856
167 + 72689 = 72856
233 + 72623 = 72856
239 + 72617 = 72856
353 + 72503 = 72856

Showing the first eight; more decompositions exist.
