Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131796, here are decompositions:

13 + 131783 = 131796
17 + 131779 = 131796
19 + 131777 = 131796
37 + 131759 = 131796
47 + 131749 = 131796
53 + 131743 = 131796
83 + 131713 = 131796
89 + 131707 = 131796

Showing the first eight; more decompositions exist.
