Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161450, here are decompositions:

43 + 161407 = 161450
73 + 161377 = 161450
109 + 161341 = 161450
127 + 161323 = 161450
229 + 161221 = 161450
283 + 161167 = 161450
313 + 161137 = 161450
379 + 161071 = 161450

Showing the first eight; more decompositions exist.
