Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11782, here are decompositions:

3 + 11779 = 11782
5 + 11777 = 11782
83 + 11699 = 11782
101 + 11681 = 11782
149 + 11633 = 11782
233 + 11549 = 11782
263 + 11519 = 11782
293 + 11489 = 11782

Showing the first eight; more decompositions exist.
