Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181792, here are decompositions:

3 + 181789 = 181792
5 + 181787 = 181792
29 + 181763 = 181792
41 + 181751 = 181792
53 + 181739 = 181792
71 + 181721 = 181792
173 + 181619 = 181792
239 + 181553 = 181792

Showing the first eight; more decompositions exist.
