Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029520, here are decompositions:

3 + 1029517 = 1029520
47 + 1029473 = 1029520
53 + 1029467 = 1029520
113 + 1029407 = 1029520
137 + 1029383 = 1029520
179 + 1029341 = 1029520
197 + 1029323 = 1029520
257 + 1029263 = 1029520

Showing the first eight; more decompositions exist.
