Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161482, here are decompositions:

11 + 161471 = 161482
23 + 161459 = 161482
29 + 161453 = 161482
71 + 161411 = 161482
149 + 161333 = 161482
173 + 161309 = 161482
179 + 161303 = 161482
281 + 161201 = 161482

Showing the first eight; more decompositions exist.
