Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164804, here are decompositions:

37 + 164767 = 164804
61 + 164743 = 164804
97 + 164707 = 164804
103 + 164701 = 164804
127 + 164677 = 164804
151 + 164653 = 164804
181 + 164623 = 164804
223 + 164581 = 164804

Showing the first eight; more decompositions exist.
