Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162842, here are decompositions:

3 + 162839 = 162842
13 + 162829 = 162842
19 + 162823 = 162842
103 + 162739 = 162842
139 + 162703 = 162842
151 + 162691 = 162842
193 + 162649 = 162842
241 + 162601 = 162842

Showing the first eight; more decompositions exist.
