Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540866, here are decompositions:

3 + 540863 = 540866
43 + 540823 = 540866
97 + 540769 = 540866
163 + 540703 = 540866
307 + 540559 = 540866
349 + 540517 = 540866
397 + 540469 = 540866
433 + 540433 = 540866

Showing the first eight; more decompositions exist.
