Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022512, here are decompositions:

3 + 1022509 = 1022512
5 + 1022507 = 1022512
11 + 1022501 = 1022512
83 + 1022429 = 1022512
131 + 1022381 = 1022512
263 + 1022249 = 1022512
269 + 1022243 = 1022512
311 + 1022201 = 1022512

Showing the first eight; more decompositions exist.
