Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162038, here are decompositions:

31 + 162007 = 162038
61 + 161977 = 162038
67 + 161971 = 162038
127 + 161911 = 162038
157 + 161881 = 162038
199 + 161839 = 162038
277 + 161761 = 162038
307 + 161731 = 162038

Showing the first eight; more decompositions exist.
