Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55040, here are decompositions:

19 + 55021 = 55040
31 + 55009 = 55040
61 + 54979 = 55040
67 + 54973 = 55040
163 + 54877 = 55040
211 + 54829 = 55040
241 + 54799 = 55040
313 + 54727 = 55040

Showing the first eight; more decompositions exist.
