Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181754, here are decompositions:

3 + 181751 = 181754
37 + 181717 = 181754
43 + 181711 = 181754
61 + 181693 = 181754
151 + 181603 = 181754
241 + 181513 = 181754
367 + 181387 = 181754
457 + 181297 = 181754

Showing the first eight; more decompositions exist.
