Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164398, here are decompositions:

11 + 164387 = 164398
41 + 164357 = 164398
89 + 164309 = 164398
107 + 164291 = 164398
131 + 164267 = 164398
149 + 164249 = 164398
167 + 164231 = 164398
197 + 164201 = 164398

Showing the first eight; more decompositions exist.
