Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025726, here are decompositions:

19 + 1025707 = 1025726
67 + 1025659 = 1025726
73 + 1025653 = 1025726
103 + 1025623 = 1025726
223 + 1025503 = 1025726
283 + 1025443 = 1025726
307 + 1025419 = 1025726
313 + 1025413 = 1025726

Showing the first eight; more decompositions exist.
