Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181734, here are decompositions:

5 + 181729 = 181734
13 + 181721 = 181734
17 + 181717 = 181734
23 + 181711 = 181734
41 + 181693 = 181734
67 + 181667 = 181734
127 + 181607 = 181734
131 + 181603 = 181734

Showing the first eight; more decompositions exist.
