Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025286, here are decompositions:

5 + 1025281 = 1025286
7 + 1025279 = 1025286
13 + 1025273 = 1025286
19 + 1025267 = 1025286
29 + 1025257 = 1025286
47 + 1025239 = 1025286
83 + 1025203 = 1025286
89 + 1025197 = 1025286

Showing the first eight; more decompositions exist.
