Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540538, here are decompositions:

29 + 540509 = 540538
101 + 540437 = 540538
149 + 540389 = 540538
191 + 540347 = 540538
269 + 540269 = 540538
359 + 540179 = 540538
389 + 540149 = 540538
419 + 540119 = 540538

Showing the first eight; more decompositions exist.
