Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19382, here are decompositions:

3 + 19379 = 19382
73 + 19309 = 19382
109 + 19273 = 19382
151 + 19231 = 19382
163 + 19219 = 19382
199 + 19183 = 19382
241 + 19141 = 19382
313 + 19069 = 19382

Showing the first eight; more decompositions exist.
