Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177982, here are decompositions:

3 + 177979 = 177982
29 + 177953 = 177982
53 + 177929 = 177982
89 + 177893 = 177982
191 + 177791 = 177982
239 + 177743 = 177982
359 + 177623 = 177982
443 + 177539 = 177982

Showing the first eight; more decompositions exist.
