Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161796, here are decompositions:

13 + 161783 = 161796
17 + 161779 = 161796
23 + 161773 = 161796
43 + 161753 = 161796
53 + 161743 = 161796
67 + 161729 = 161796
79 + 161717 = 161796
113 + 161683 = 161796

Showing the first eight; more decompositions exist.
