Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515272, here are decompositions:

41 + 515231 = 515272
383 + 514889 = 515272
419 + 514853 = 515272
431 + 514841 = 515272
449 + 514823 = 515272
479 + 514793 = 515272
503 + 514769 = 515272
521 + 514751 = 515272

Showing the first eight; more decompositions exist.
