Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185722, here are decompositions:

11 + 185711 = 185722
23 + 185699 = 185722
29 + 185693 = 185722
41 + 185681 = 185722
71 + 185651 = 185722
101 + 185621 = 185722
179 + 185543 = 185722
191 + 185531 = 185722

Showing the first eight; more decompositions exist.
