Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19718, here are decompositions:

19 + 19699 = 19718
31 + 19687 = 19718
37 + 19681 = 19718
109 + 19609 = 19718
211 + 19507 = 19718
229 + 19489 = 19718
241 + 19477 = 19718
271 + 19447 = 19718

Showing the first eight; more decompositions exist.
