Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185930, here are decompositions:

7 + 185923 = 185930
13 + 185917 = 185930
37 + 185893 = 185930
61 + 185869 = 185930
97 + 185833 = 185930
109 + 185821 = 185930
163 + 185767 = 185930
181 + 185749 = 185930

Showing the first eight; more decompositions exist.
