Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161422, here are decompositions:

11 + 161411 = 161422
59 + 161363 = 161422
83 + 161339 = 161422
89 + 161333 = 161422
113 + 161309 = 161422
263 + 161159 = 161422
281 + 161141 = 161422
383 + 161039 = 161422

Showing the first eight; more decompositions exist.
