Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540874, here are decompositions:

3 + 540871 = 540874
11 + 540863 = 540874
23 + 540851 = 540874
71 + 540803 = 540874
101 + 540773 = 540874
197 + 540677 = 540874
263 + 540611 = 540874
317 + 540557 = 540874

Showing the first eight; more decompositions exist.
