Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161746, here are decompositions:

3 + 161743 = 161746
5 + 161741 = 161746
17 + 161729 = 161746
29 + 161717 = 161746
107 + 161639 = 161746
173 + 161573 = 161746
239 + 161507 = 161746
293 + 161453 = 161746

Showing the first eight; more decompositions exist.
