Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021512, here are decompositions:

29 + 1021483 = 1021512
71 + 1021441 = 1021512
83 + 1021429 = 1021512
109 + 1021403 = 1021512
131 + 1021381 = 1021512
139 + 1021373 = 1021512
179 + 1021333 = 1021512
181 + 1021331 = 1021512

Showing the first eight; more decompositions exist.
