Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161306, here are decompositions:

3 + 161303 = 161306
43 + 161263 = 161306
73 + 161233 = 161306
139 + 161167 = 161306
157 + 161149 = 161306
337 + 160969 = 161306
373 + 160933 = 161306
499 + 160807 = 161306

Showing the first eight; more decompositions exist.
