Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56990, here are decompositions:

7 + 56983 = 56990
61 + 56929 = 56990
67 + 56923 = 56990
79 + 56911 = 56990
97 + 56893 = 56990
163 + 56827 = 56990
181 + 56809 = 56990
211 + 56779 = 56990

Showing the first eight; more decompositions exist.
