Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501520, here are decompositions:

17 + 501503 = 501520
101 + 501419 = 501520
137 + 501383 = 501520
179 + 501341 = 501520
233 + 501287 = 501520
263 + 501257 = 501520
311 + 501209 = 501520
317 + 501203 = 501520

Showing the first eight; more decompositions exist.
