Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540406, here are decompositions:

17 + 540389 = 540406
23 + 540383 = 540406
29 + 540377 = 540406
59 + 540347 = 540406
137 + 540269 = 540406
173 + 540233 = 540406
227 + 540179 = 540406
233 + 540173 = 540406

Showing the first eight; more decompositions exist.
