Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540378, here are decompositions:

5 + 540373 = 540378
11 + 540367 = 540378
29 + 540349 = 540378
31 + 540347 = 540378
71 + 540307 = 540378
107 + 540271 = 540378
109 + 540269 = 540378
127 + 540251 = 540378

Showing the first eight; more decompositions exist.
