Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020726, here are decompositions:

17 + 1020709 = 1020726
19 + 1020707 = 1020726
37 + 1020689 = 1020726
43 + 1020683 = 1020726
59 + 1020667 = 1020726
107 + 1020619 = 1020726
127 + 1020599 = 1020726
137 + 1020589 = 1020726

Showing the first eight; more decompositions exist.
