Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540566, here are decompositions:

7 + 540559 = 540566
97 + 540469 = 540566
193 + 540373 = 540566
199 + 540367 = 540566
223 + 540343 = 540566
283 + 540283 = 540566
349 + 540217 = 540566
379 + 540187 = 540566

Showing the first eight; more decompositions exist.
