Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164260, here are decompositions:

11 + 164249 = 164260
29 + 164231 = 164260
59 + 164201 = 164260
113 + 164147 = 164260
167 + 164093 = 164260
263 + 163997 = 164260
269 + 163991 = 164260
281 + 163979 = 164260

Showing the first eight; more decompositions exist.
