Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167838, here are decompositions:

29 + 167809 = 167838
37 + 167801 = 167838
59 + 167779 = 167838
61 + 167777 = 167838
67 + 167771 = 167838
79 + 167759 = 167838
109 + 167729 = 167838
127 + 167711 = 167838

Showing the first eight; more decompositions exist.
