Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55818, here are decompositions:

5 + 55813 = 55818
11 + 55807 = 55818
19 + 55799 = 55818
31 + 55787 = 55818
97 + 55721 = 55818
101 + 55717 = 55818
107 + 55711 = 55818
127 + 55691 = 55818

Showing the first eight; more decompositions exist.
