Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42162, here are decompositions:

5 + 42157 = 42162
23 + 42139 = 42162
31 + 42131 = 42162
61 + 42101 = 42162
73 + 42089 = 42162
79 + 42083 = 42162
89 + 42073 = 42162
101 + 42061 = 42162

Showing the first eight; more decompositions exist.
