Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939144, here are decompositions:

23 + 939121 = 939144
53 + 939091 = 939144
83 + 939061 = 939144
137 + 939007 = 939144
163 + 938981 = 939144
181 + 938963 = 939144
191 + 938953 = 939144
197 + 938947 = 939144

Showing the first eight; more decompositions exist.
