Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540838, here are decompositions:

29 + 540809 = 540838
59 + 540779 = 540838
149 + 540689 = 540838
227 + 540611 = 540838
239 + 540599 = 540838
251 + 540587 = 540838
281 + 540557 = 540838
401 + 540437 = 540838

Showing the first eight; more decompositions exist.
