Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55840, here are decompositions:

3 + 55837 = 55840
11 + 55829 = 55840
17 + 55823 = 55840
23 + 55817 = 55840
41 + 55799 = 55840
47 + 55793 = 55840
53 + 55787 = 55840
107 + 55733 = 55840

Showing the first eight; more decompositions exist.
