Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131792, here are decompositions:

13 + 131779 = 131792
43 + 131749 = 131792
61 + 131731 = 131792
79 + 131713 = 131792
151 + 131641 = 131792
181 + 131611 = 131792
211 + 131581 = 131792
313 + 131479 = 131792

Showing the first eight; more decompositions exist.
