Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164284, here are decompositions:

5 + 164279 = 164284
17 + 164267 = 164284
53 + 164231 = 164284
83 + 164201 = 164284
101 + 164183 = 164284
137 + 164147 = 164284
167 + 164117 = 164284
191 + 164093 = 164284

Showing the first eight; more decompositions exist.
