Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164690, here are decompositions:

7 + 164683 = 164690
13 + 164677 = 164690
37 + 164653 = 164690
67 + 164623 = 164690
73 + 164617 = 164690
103 + 164587 = 164690
109 + 164581 = 164690
241 + 164449 = 164690

Showing the first eight; more decompositions exist.
