Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540886, here are decompositions:

23 + 540863 = 540886
83 + 540803 = 540886
107 + 540779 = 540886
113 + 540773 = 540886
173 + 540713 = 540886
197 + 540689 = 540886
257 + 540629 = 540886
347 + 540539 = 540886

Showing the first eight; more decompositions exist.
