Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180976, here are decompositions:

17 + 180959 = 180976
179 + 180797 = 180976
197 + 180779 = 180976
227 + 180749 = 180976
347 + 180629 = 180976
353 + 180623 = 180976
359 + 180617 = 180976
443 + 180533 = 180976

Showing the first eight; more decompositions exist.
