Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185980, here are decompositions:

23 + 185957 = 185980
29 + 185951 = 185980
83 + 185897 = 185980
107 + 185873 = 185980
131 + 185849 = 185980
149 + 185831 = 185980
167 + 185813 = 185980
191 + 185789 = 185980

Showing the first eight; more decompositions exist.
