Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167980, here are decompositions:

89 + 167891 = 167980
101 + 167879 = 167980
107 + 167873 = 167980
179 + 167801 = 167980
233 + 167747 = 167980
251 + 167729 = 167980
269 + 167711 = 167980
317 + 167663 = 167980

Showing the first eight; more decompositions exist.
