Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540442, here are decompositions:

5 + 540437 = 540442
53 + 540389 = 540442
59 + 540383 = 540442
173 + 540269 = 540442
191 + 540251 = 540442
239 + 540203 = 540442
263 + 540179 = 540442
269 + 540173 = 540442

Showing the first eight; more decompositions exist.
