Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161350, here are decompositions:

11 + 161339 = 161350
17 + 161333 = 161350
41 + 161309 = 161350
47 + 161303 = 161350
83 + 161267 = 161350
113 + 161237 = 161350
149 + 161201 = 161350
191 + 161159 = 161350

Showing the first eight; more decompositions exist.
