Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176990, here are decompositions:

7 + 176983 = 176990
13 + 176977 = 176990
67 + 176923 = 176990
103 + 176887 = 176990
181 + 176809 = 176990
193 + 176797 = 176990
199 + 176791 = 176990
211 + 176779 = 176990

Showing the first eight; more decompositions exist.
