Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540388, here are decompositions:

5 + 540383 = 540388
11 + 540377 = 540388
41 + 540347 = 540388
137 + 540251 = 540388
239 + 540149 = 540388
269 + 540119 = 540388
347 + 540041 = 540388
467 + 539921 = 540388

Showing the first eight; more decompositions exist.
