Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164184, here are decompositions:

11 + 164173 = 164184
37 + 164147 = 164184
67 + 164117 = 164184
71 + 164113 = 164184
113 + 164071 = 164184
127 + 164057 = 164184
173 + 164011 = 164184
191 + 163993 = 164184

Showing the first eight; more decompositions exist.
