Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022506, here are decompositions:

3 + 1022503 = 1022506
5 + 1022501 = 1022506
257 + 1022249 = 1022506
263 + 1022243 = 1022506
269 + 1022237 = 1022506
383 + 1022123 = 1022506
587 + 1021919 = 1022506
599 + 1021907 = 1022506

Showing the first eight; more decompositions exist.
