Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540408, here are decompositions:

17 + 540391 = 540408
19 + 540389 = 540408
31 + 540377 = 540408
41 + 540367 = 540408
59 + 540349 = 540408
61 + 540347 = 540408
101 + 540307 = 540408
107 + 540301 = 540408

Showing the first eight; more decompositions exist.
