Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161794, here are decompositions:

11 + 161783 = 161794
23 + 161771 = 161794
41 + 161753 = 161794
53 + 161741 = 161794
167 + 161627 = 161794
233 + 161561 = 161794
251 + 161543 = 161794
263 + 161531 = 161794

Showing the first eight; more decompositions exist.
