Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161232, here are decompositions:

11 + 161221 = 161232
31 + 161201 = 161232
73 + 161159 = 161232
83 + 161149 = 161232
109 + 161123 = 161232
139 + 161093 = 161232
173 + 161059 = 161232
179 + 161053 = 161232

Showing the first eight; more decompositions exist.
