Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185782, here are decompositions:

29 + 185753 = 185782
59 + 185723 = 185782
71 + 185711 = 185782
83 + 185699 = 185782
89 + 185693 = 185782
101 + 185681 = 185782
131 + 185651 = 185782
239 + 185543 = 185782

Showing the first eight; more decompositions exist.
