Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55810, here are decompositions:

3 + 55807 = 55810
11 + 55799 = 55810
17 + 55793 = 55810
23 + 55787 = 55810
47 + 55763 = 55810
89 + 55721 = 55810
113 + 55697 = 55810
137 + 55673 = 55810

Showing the first eight; more decompositions exist.
