Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164688, here are decompositions:

5 + 164683 = 164688
11 + 164677 = 164688
61 + 164627 = 164688
67 + 164621 = 164688
71 + 164617 = 164688
89 + 164599 = 164688
101 + 164587 = 164688
107 + 164581 = 164688

Showing the first eight; more decompositions exist.
