Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025806, here are decompositions:

3 + 1025803 = 1025806
17 + 1025789 = 1025806
59 + 1025747 = 1025806
113 + 1025693 = 1025806
137 + 1025669 = 1025806
227 + 1025579 = 1025806
263 + 1025543 = 1025806
269 + 1025537 = 1025806

Showing the first eight; more decompositions exist.
