Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164660, here are decompositions:

7 + 164653 = 164660
37 + 164623 = 164660
43 + 164617 = 164660
61 + 164599 = 164660
73 + 164587 = 164660
79 + 164581 = 164660
157 + 164503 = 164660
211 + 164449 = 164660

Showing the first eight; more decompositions exist.
