Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025678, here are decompositions:

19 + 1025659 = 1025678
37 + 1025641 = 1025678
67 + 1025611 = 1025678
127 + 1025551 = 1025678
271 + 1025407 = 1025678
331 + 1025347 = 1025678
397 + 1025281 = 1025678
421 + 1025257 = 1025678

Showing the first eight; more decompositions exist.
