Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164942, here are decompositions:

31 + 164911 = 164942
61 + 164881 = 164942
103 + 164839 = 164942
199 + 164743 = 164942
241 + 164701 = 164942
373 + 164569 = 164942
439 + 164503 = 164942
499 + 164443 = 164942

Showing the first eight; more decompositions exist.
