Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540404, here are decompositions:

13 + 540391 = 540404
31 + 540373 = 540404
37 + 540367 = 540404
61 + 540343 = 540404
97 + 540307 = 540404
103 + 540301 = 540404
223 + 540181 = 540404
283 + 540121 = 540404

Showing the first eight; more decompositions exist.
