Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162866, here are decompositions:

7 + 162859 = 162866
13 + 162853 = 162866
19 + 162847 = 162866
37 + 162829 = 162866
43 + 162823 = 162866
79 + 162787 = 162866
127 + 162739 = 162866
139 + 162727 = 162866

Showing the first eight; more decompositions exist.
