Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19792, here are decompositions:

29 + 19763 = 19792
41 + 19751 = 19792
53 + 19739 = 19792
83 + 19709 = 19792
131 + 19661 = 19792
233 + 19559 = 19792
239 + 19553 = 19792
251 + 19541 = 19792

Showing the first eight; more decompositions exist.
