Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540518, here are decompositions:

7 + 540511 = 540518
127 + 540391 = 540518
151 + 540367 = 540518
211 + 540307 = 540518
331 + 540187 = 540518
337 + 540181 = 540518
379 + 540139 = 540518
397 + 540121 = 540518

Showing the first eight; more decompositions exist.
