Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025858, here are decompositions:

19 + 1025839 = 1025858
109 + 1025749 = 1025858
151 + 1025707 = 1025858
199 + 1025659 = 1025858
307 + 1025551 = 1025858
349 + 1025509 = 1025858
439 + 1025419 = 1025858
577 + 1025281 = 1025858

Showing the first eight; more decompositions exist.
