Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162942, here are decompositions:

5 + 162937 = 162942
41 + 162901 = 162942
53 + 162889 = 162942
61 + 162881 = 162942
83 + 162859 = 162942
89 + 162853 = 162942
103 + 162839 = 162942
113 + 162829 = 162942

Showing the first eight; more decompositions exist.
