Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19550, here are decompositions:

7 + 19543 = 19550
19 + 19531 = 19550
43 + 19507 = 19550
61 + 19489 = 19550
67 + 19483 = 19550
73 + 19477 = 19550
79 + 19471 = 19550
103 + 19447 = 19550

Showing the first eight; more decompositions exist.
