Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162194, here are decompositions:

103 + 162091 = 162194
211 + 161983 = 162194
223 + 161971 = 162194
271 + 161923 = 162194
283 + 161911 = 162194
313 + 161881 = 162194
421 + 161773 = 162194
433 + 161761 = 162194

Showing the first eight; more decompositions exist.
