Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164980, here are decompositions:

17 + 164963 = 164980
149 + 164831 = 164980
191 + 164789 = 164980
251 + 164729 = 164980
317 + 164663 = 164980
353 + 164627 = 164980
359 + 164621 = 164980
449 + 164531 = 164980

Showing the first eight; more decompositions exist.
