Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164972, here are decompositions:

19 + 164953 = 164972
61 + 164911 = 164972
79 + 164893 = 164972
151 + 164821 = 164972
163 + 164809 = 164972
229 + 164743 = 164972
271 + 164701 = 164972
349 + 164623 = 164972

Showing the first eight; more decompositions exist.
