Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538018, here are decompositions:

17 + 538001 = 538018
269 + 537749 = 538018
419 + 537599 = 538018
431 + 537587 = 538018
449 + 537569 = 538018
491 + 537527 = 538018
521 + 537497 = 538018
617 + 537401 = 538018

Showing the first eight; more decompositions exist.
