Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025538, here are decompositions:

29 + 1025509 = 1025538
61 + 1025477 = 1025538
79 + 1025459 = 1025538
131 + 1025407 = 1025538
191 + 1025347 = 1025538
211 + 1025327 = 1025538
257 + 1025281 = 1025538
271 + 1025267 = 1025538

Showing the first eight; more decompositions exist.
