Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19448, here are decompositions:

7 + 19441 = 19448
19 + 19429 = 19448
31 + 19417 = 19448
61 + 19387 = 19448
67 + 19381 = 19448
139 + 19309 = 19448
181 + 19267 = 19448
199 + 19249 = 19448

Showing the first eight; more decompositions exist.
