Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162438, here are decompositions:

19 + 162419 = 162438
47 + 162391 = 162438
79 + 162359 = 162438
149 + 162289 = 162438
151 + 162287 = 162438
181 + 162257 = 162438
229 + 162209 = 162438
347 + 162091 = 162438

Showing the first eight; more decompositions exist.
