Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025836, here are decompositions:

17 + 1025819 = 1025836
29 + 1025807 = 1025836
47 + 1025789 = 1025836
89 + 1025747 = 1025836
167 + 1025669 = 1025836
257 + 1025579 = 1025836
293 + 1025543 = 1025836
353 + 1025483 = 1025836

Showing the first eight; more decompositions exist.
