Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164816, here are decompositions:

7 + 164809 = 164816
73 + 164743 = 164816
109 + 164707 = 164816
139 + 164677 = 164816
163 + 164653 = 164816
193 + 164623 = 164816
199 + 164617 = 164816
229 + 164587 = 164816

Showing the first eight; more decompositions exist.
