Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162518, here are decompositions:

19 + 162499 = 162518
61 + 162457 = 162518
67 + 162451 = 162518
79 + 162439 = 162518
127 + 162391 = 162518
229 + 162289 = 162518
241 + 162277 = 162518
409 + 162109 = 162518

Showing the first eight; more decompositions exist.
