Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185998, here are decompositions:

5 + 185993 = 185998
11 + 185987 = 185998
41 + 185957 = 185998
47 + 185951 = 185998
101 + 185897 = 185998
149 + 185849 = 185998
167 + 185831 = 185998
179 + 185819 = 185998

Showing the first eight; more decompositions exist.
