Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164888, here are decompositions:

7 + 164881 = 164888
67 + 164821 = 164888
79 + 164809 = 164888
181 + 164707 = 164888
211 + 164677 = 164888
271 + 164617 = 164888
307 + 164581 = 164888
439 + 164449 = 164888

Showing the first eight; more decompositions exist.
