Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162412, here are decompositions:

23 + 162389 = 162412
53 + 162359 = 162412
149 + 162263 = 162412
191 + 162221 = 162412
269 + 162143 = 162412
293 + 162119 = 162412
353 + 162059 = 162412
359 + 162053 = 162412

Showing the first eight; more decompositions exist.
