Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19268, here are decompositions:

19 + 19249 = 19268
31 + 19237 = 19268
37 + 19231 = 19268
61 + 19207 = 19268
127 + 19141 = 19268
181 + 19087 = 19268
199 + 19069 = 19268
349 + 18919 = 19268

Showing the first eight; more decompositions exist.
