Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164392, here are decompositions:

5 + 164387 = 164392
29 + 164363 = 164392
71 + 164321 = 164392
83 + 164309 = 164392
101 + 164291 = 164392
113 + 164279 = 164392
191 + 164201 = 164392
353 + 164039 = 164392

Showing the first eight; more decompositions exist.
