Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164358, here are decompositions:

17 + 164341 = 164358
37 + 164321 = 164358
59 + 164299 = 164358
67 + 164291 = 164358
79 + 164279 = 164358
107 + 164251 = 164358
109 + 164249 = 164358
127 + 164231 = 164358

Showing the first eight; more decompositions exist.
