Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160042, here are decompositions:

11 + 160031 = 160042
23 + 160019 = 160042
41 + 160001 = 160042
131 + 159911 = 160042
173 + 159869 = 160042
251 + 159791 = 160042
263 + 159779 = 160042
269 + 159773 = 160042

Showing the first eight; more decompositions exist.
