Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162458, here are decompositions:

7 + 162451 = 162458
19 + 162439 = 162458
67 + 162391 = 162458
181 + 162277 = 162458
229 + 162229 = 162458
349 + 162109 = 162458
367 + 162091 = 162458
379 + 162079 = 162458

Showing the first eight; more decompositions exist.
