Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162906, here are decompositions:

5 + 162901 = 162906
17 + 162889 = 162906
47 + 162859 = 162906
53 + 162853 = 162906
59 + 162847 = 162906
67 + 162839 = 162906
83 + 162823 = 162906
127 + 162779 = 162906

Showing the first eight; more decompositions exist.
