Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025126, here are decompositions:

7 + 1025119 = 1025126
13 + 1025113 = 1025126
79 + 1025047 = 1025126
97 + 1025029 = 1025126
139 + 1024987 = 1025126
163 + 1024963 = 1025126
283 + 1024843 = 1025126
397 + 1024729 = 1025126

Showing the first eight; more decompositions exist.
