Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161484, here are decompositions:

13 + 161471 = 161484
23 + 161461 = 161484
31 + 161453 = 161484
73 + 161411 = 161484
97 + 161387 = 161484
107 + 161377 = 161484
151 + 161333 = 161484
181 + 161303 = 161484

Showing the first eight; more decompositions exist.
