Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19316, here are decompositions:

7 + 19309 = 19316
43 + 19273 = 19316
67 + 19249 = 19316
79 + 19237 = 19316
97 + 19219 = 19316
103 + 19213 = 19316
109 + 19207 = 19316
229 + 19087 = 19316

Showing the first eight; more decompositions exist.
