Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164912, here are decompositions:

19 + 164893 = 164912
31 + 164881 = 164912
73 + 164839 = 164912
103 + 164809 = 164912
211 + 164701 = 164912
229 + 164683 = 164912
313 + 164599 = 164912
331 + 164581 = 164912

Showing the first eight; more decompositions exist.
