Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164020, here are decompositions:

23 + 163997 = 164020
29 + 163991 = 164020
41 + 163979 = 164020
47 + 163973 = 164020
137 + 163883 = 164020
149 + 163871 = 164020
167 + 163853 = 164020
173 + 163847 = 164020

Showing the first eight; more decompositions exist.
