Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018726, here are decompositions:

17 + 1018709 = 1018726
29 + 1018697 = 1018726
47 + 1018679 = 1018726
53 + 1018673 = 1018726
83 + 1018643 = 1018726
113 + 1018613 = 1018726
167 + 1018559 = 1018726
389 + 1018337 = 1018726

Showing the first eight; more decompositions exist.
