Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164210, here are decompositions:

19 + 164191 = 164210
37 + 164173 = 164210
61 + 164149 = 164210
97 + 164113 = 164210
139 + 164071 = 164210
199 + 164011 = 164210
223 + 163987 = 164210
229 + 163981 = 164210

Showing the first eight; more decompositions exist.
