Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181934, here are decompositions:

3 + 181931 = 181934
7 + 181927 = 181934
31 + 181903 = 181934
43 + 181891 = 181934
61 + 181873 = 181934
97 + 181837 = 181934
157 + 181777 = 181934
223 + 181711 = 181934

Showing the first eight; more decompositions exist.
