Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536666, here are decompositions:

73 + 536593 = 536666
103 + 536563 = 536666
157 + 536509 = 536666
199 + 536467 = 536666
223 + 536443 = 536666
313 + 536353 = 536666
373 + 536293 = 536666
379 + 536287 = 536666

Showing the first eight; more decompositions exist.
