Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185812, here are decompositions:

23 + 185789 = 185812
59 + 185753 = 185812
89 + 185723 = 185812
101 + 185711 = 185812
113 + 185699 = 185812
131 + 185681 = 185812
191 + 185621 = 185812
269 + 185543 = 185812

Showing the first eight; more decompositions exist.
