Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515104, here are decompositions:

17 + 515087 = 515104
137 + 514967 = 515104
251 + 514853 = 515104
257 + 514847 = 515104
263 + 514841 = 515104
281 + 514823 = 515104
311 + 514793 = 515104
347 + 514757 = 515104

Showing the first eight; more decompositions exist.
