Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164904, here are decompositions:

11 + 164893 = 164904
23 + 164881 = 164904
67 + 164837 = 164904
73 + 164831 = 164904
83 + 164821 = 164904
137 + 164767 = 164904
197 + 164707 = 164904
227 + 164677 = 164904

Showing the first eight; more decompositions exist.
