Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540520, here are decompositions:

3 + 540517 = 540520
11 + 540509 = 540520
59 + 540461 = 540520
83 + 540437 = 540520
131 + 540389 = 540520
137 + 540383 = 540520
173 + 540347 = 540520
251 + 540269 = 540520

Showing the first eight; more decompositions exist.
