Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55828, here are decompositions:

5 + 55823 = 55828
11 + 55817 = 55828
29 + 55799 = 55828
41 + 55787 = 55828
107 + 55721 = 55828
131 + 55697 = 55828
137 + 55691 = 55828
167 + 55661 = 55828

Showing the first eight; more decompositions exist.
