Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540420, here are decompositions:

29 + 540391 = 540420
31 + 540389 = 540420
37 + 540383 = 540420
43 + 540377 = 540420
47 + 540373 = 540420
53 + 540367 = 540420
71 + 540349 = 540420
73 + 540347 = 540420

Showing the first eight; more decompositions exist.
