Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161264, here are decompositions:

31 + 161233 = 161264
43 + 161221 = 161264
97 + 161167 = 161264
127 + 161137 = 161264
193 + 161071 = 161264
211 + 161053 = 161264
283 + 160981 = 161264
331 + 160933 = 161264

Showing the first eight; more decompositions exist.
