Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515126, here are decompositions:

37 + 515089 = 515126
193 + 514933 = 515126
223 + 514903 = 515126
307 + 514819 = 515126
379 + 514747 = 515126
457 + 514669 = 515126
487 + 514639 = 515126
607 + 514519 = 515126

Showing the first eight; more decompositions exist.
