Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55816, here are decompositions:

3 + 55813 = 55816
17 + 55799 = 55816
23 + 55793 = 55816
29 + 55787 = 55816
53 + 55763 = 55816
83 + 55733 = 55816
149 + 55667 = 55816
197 + 55619 = 55816

Showing the first eight; more decompositions exist.
