Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161340, here are decompositions:

7 + 161333 = 161340
17 + 161323 = 161340
31 + 161309 = 161340
37 + 161303 = 161340
59 + 161281 = 161340
73 + 161267 = 161340
103 + 161237 = 161340
107 + 161233 = 161340

Showing the first eight; more decompositions exist.
