Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516478, here are decompositions:

29 + 516449 = 516478
41 + 516437 = 516478
47 + 516431 = 516478
71 + 516407 = 516478
101 + 516377 = 516478
107 + 516371 = 516478
227 + 516251 = 516478
251 + 516227 = 516478

Showing the first eight; more decompositions exist.
