Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167138, here are decompositions:

19 + 167119 = 167138
31 + 167107 = 167138
61 + 167077 = 167138
67 + 167071 = 167138
151 + 166987 = 167138
229 + 166909 = 167138
271 + 166867 = 167138
277 + 166861 = 167138

Showing the first eight; more decompositions exist.
