Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164858, here are decompositions:

19 + 164839 = 164858
37 + 164821 = 164858
151 + 164707 = 164858
157 + 164701 = 164858
181 + 164677 = 164858
241 + 164617 = 164858
271 + 164587 = 164858
277 + 164581 = 164858

Showing the first eight; more decompositions exist.
