Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162642, here are decompositions:

13 + 162629 = 162642
19 + 162623 = 162642
31 + 162611 = 162642
41 + 162601 = 162642
79 + 162563 = 162642
89 + 162553 = 162642
113 + 162529 = 162642
149 + 162493 = 162642

Showing the first eight; more decompositions exist.
