Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176820, here are decompositions:

11 + 176809 = 176820
13 + 176807 = 176820
23 + 176797 = 176820
29 + 176791 = 176820
31 + 176789 = 176820
41 + 176779 = 176820
43 + 176777 = 176820
67 + 176753 = 176820

Showing the first eight; more decompositions exist.
