Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025386, here are decompositions:

3 + 1025383 = 1025386
53 + 1025333 = 1025386
59 + 1025327 = 1025386
83 + 1025303 = 1025386
107 + 1025279 = 1025386
113 + 1025273 = 1025386
233 + 1025153 = 1025386
239 + 1025147 = 1025386

Showing the first eight; more decompositions exist.
