Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540664, here are decompositions:

53 + 540611 = 540664
107 + 540557 = 540664
227 + 540437 = 540664
281 + 540383 = 540664
317 + 540347 = 540664
431 + 540233 = 540664
461 + 540203 = 540664
491 + 540173 = 540664

Showing the first eight; more decompositions exist.
