Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54540, here are decompositions:

19 + 54521 = 54540
23 + 54517 = 54540
37 + 54503 = 54540
41 + 54499 = 54540
43 + 54497 = 54540
47 + 54493 = 54540
71 + 54469 = 54540
97 + 54443 = 54540

Showing the first eight; more decompositions exist.
