Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19412, here are decompositions:

31 + 19381 = 19412
79 + 19333 = 19412
103 + 19309 = 19412
139 + 19273 = 19412
163 + 19249 = 19412
181 + 19231 = 19412
193 + 19219 = 19412
199 + 19213 = 19412

Showing the first eight; more decompositions exist.
