Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025866, here are decompositions:

47 + 1025819 = 1025866
59 + 1025807 = 1025866
173 + 1025693 = 1025866
197 + 1025669 = 1025866
353 + 1025513 = 1025866
383 + 1025483 = 1025866
389 + 1025477 = 1025866
449 + 1025417 = 1025866

Showing the first eight; more decompositions exist.
