Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025406, here are decompositions:

13 + 1025393 = 1025406
23 + 1025383 = 1025406
59 + 1025347 = 1025406
73 + 1025333 = 1025406
79 + 1025327 = 1025406
103 + 1025303 = 1025406
127 + 1025279 = 1025406
139 + 1025267 = 1025406

Showing the first eight; more decompositions exist.
