Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517120, here are decompositions:

29 + 517091 = 517120
41 + 517079 = 517120
47 + 517073 = 517120
53 + 517067 = 517120
59 + 517061 = 517120
173 + 516947 = 517120
281 + 516839 = 517120
419 + 516701 = 517120

Showing the first eight; more decompositions exist.
