Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164066, here are decompositions:

43 + 164023 = 164066
73 + 163993 = 164066
79 + 163987 = 164066
139 + 163927 = 164066
157 + 163909 = 164066
277 + 163789 = 164066
313 + 163753 = 164066
337 + 163729 = 164066

Showing the first eight; more decompositions exist.
