Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025494, here are decompositions:

11 + 1025483 = 1025494
17 + 1025477 = 1025494
101 + 1025393 = 1025494
167 + 1025327 = 1025494
191 + 1025303 = 1025494
227 + 1025267 = 1025494
233 + 1025261 = 1025494
263 + 1025231 = 1025494

Showing the first eight; more decompositions exist.
