Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164228, here are decompositions:

19 + 164209 = 164228
37 + 164191 = 164228
79 + 164149 = 164228
139 + 164089 = 164228
157 + 164071 = 164228
241 + 163987 = 164228
367 + 163861 = 164228
409 + 163819 = 164228

Showing the first eight; more decompositions exist.
