Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56900, here are decompositions:

3 + 56897 = 56900
7 + 56893 = 56900
43 + 56857 = 56900
73 + 56827 = 56900
79 + 56821 = 56900
127 + 56773 = 56900
163 + 56737 = 56900
199 + 56701 = 56900

Showing the first eight; more decompositions exist.
