Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162402, here are decompositions:

11 + 162391 = 162402
13 + 162389 = 162402
43 + 162359 = 162402
59 + 162343 = 162402
109 + 162293 = 162402
113 + 162289 = 162402
139 + 162263 = 162402
151 + 162251 = 162402

Showing the first eight; more decompositions exist.
