Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025870, here are decompositions:

31 + 1025839 = 1025870
67 + 1025803 = 1025870
103 + 1025767 = 1025870
163 + 1025707 = 1025870
211 + 1025659 = 1025870
229 + 1025641 = 1025870
367 + 1025503 = 1025870
457 + 1025413 = 1025870

Showing the first eight; more decompositions exist.
