Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939186, here are decompositions:

5 + 939181 = 939186
7 + 939179 = 939186
19 + 939167 = 939186
29 + 939157 = 939186
67 + 939119 = 939186
97 + 939089 = 939186
167 + 939019 = 939186
179 + 939007 = 939186

Showing the first eight; more decompositions exist.
