Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162938, here are decompositions:

31 + 162907 = 162938
37 + 162901 = 162938
79 + 162859 = 162938
109 + 162829 = 162938
151 + 162787 = 162938
199 + 162739 = 162938
211 + 162727 = 162938
229 + 162709 = 162938

Showing the first eight; more decompositions exist.
