Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161336, here are decompositions:

3 + 161333 = 161336
13 + 161323 = 161336
73 + 161263 = 161336
103 + 161233 = 161336
199 + 161137 = 161336
277 + 161059 = 161336
283 + 161053 = 161336
367 + 160969 = 161336

Showing the first eight; more decompositions exist.
