Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162570, here are decompositions:

7 + 162563 = 162570
13 + 162557 = 162570
17 + 162553 = 162570
41 + 162529 = 162570
43 + 162527 = 162570
47 + 162523 = 162570
53 + 162517 = 162570
71 + 162499 = 162570

Showing the first eight; more decompositions exist.
