Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508720, here are decompositions:

11 + 508709 = 508720
59 + 508661 = 508720
83 + 508637 = 508720
101 + 508619 = 508720
137 + 508583 = 508720
269 + 508451 = 508720
281 + 508439 = 508720
347 + 508373 = 508720

Showing the first eight; more decompositions exist.
