Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162418, here are decompositions:

5 + 162413 = 162418
29 + 162389 = 162418
59 + 162359 = 162418
131 + 162287 = 162418
149 + 162269 = 162418
167 + 162251 = 162418
197 + 162221 = 162418
359 + 162059 = 162418

Showing the first eight; more decompositions exist.
