Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164812, here are decompositions:

3 + 164809 = 164812
23 + 164789 = 164812
41 + 164771 = 164812
83 + 164729 = 164812
149 + 164663 = 164812
191 + 164621 = 164812
281 + 164531 = 164812
383 + 164429 = 164812

Showing the first eight; more decompositions exist.
