Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181794, here are decompositions:

5 + 181789 = 181794
7 + 181787 = 181794
17 + 181777 = 181794
31 + 181763 = 181794
37 + 181757 = 181794
43 + 181751 = 181794
73 + 181721 = 181794
83 + 181711 = 181794

Showing the first eight; more decompositions exist.
