Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19748, here are decompositions:

31 + 19717 = 19748
61 + 19687 = 19748
67 + 19681 = 19748
139 + 19609 = 19748
151 + 19597 = 19748
241 + 19507 = 19748
271 + 19477 = 19748
277 + 19471 = 19748

Showing the first eight; more decompositions exist.
