Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165788, here are decompositions:

67 + 165721 = 165788
79 + 165709 = 165788
199 + 165589 = 165788
229 + 165559 = 165788
277 + 165511 = 165788
331 + 165457 = 165788
397 + 165391 = 165788
409 + 165379 = 165788

Showing the first eight; more decompositions exist.
