Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162506, here are decompositions:

7 + 162499 = 162506
13 + 162493 = 162506
67 + 162439 = 162506
163 + 162343 = 162506
229 + 162277 = 162506
277 + 162229 = 162506
397 + 162109 = 162506
499 + 162007 = 162506

Showing the first eight; more decompositions exist.
