Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515224, here are decompositions:

71 + 515153 = 515224
113 + 515111 = 515224
137 + 515087 = 515224
257 + 514967 = 515224
383 + 514841 = 515224
401 + 514823 = 515224
431 + 514793 = 515224
467 + 514757 = 515224

Showing the first eight; more decompositions exist.
