Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527540, here are decompositions:

7 + 527533 = 527540
163 + 527377 = 527540
193 + 527347 = 527540
331 + 527209 = 527540
337 + 527203 = 527540
367 + 527173 = 527540
379 + 527161 = 527540
397 + 527143 = 527540

Showing the first eight; more decompositions exist.
