Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164992, here are decompositions:

5 + 164987 = 164992
29 + 164963 = 164992
263 + 164729 = 164992
461 + 164531 = 164992
479 + 164513 = 164992
521 + 164471 = 164992
563 + 164429 = 164992
683 + 164309 = 164992

Showing the first eight; more decompositions exist.
