Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165758, here are decompositions:

37 + 165721 = 165758
157 + 165601 = 165758
199 + 165559 = 165758
367 + 165391 = 165758
379 + 165379 = 165758
409 + 165349 = 165758
547 + 165211 = 165758
577 + 165181 = 165758

Showing the first eight; more decompositions exist.
