Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021726, here are decompositions:

29 + 1021697 = 1021726
53 + 1021673 = 1021726
149 + 1021577 = 1021726
239 + 1021487 = 1021726
263 + 1021463 = 1021726
269 + 1021457 = 1021726
353 + 1021373 = 1021726
359 + 1021367 = 1021726

Showing the first eight; more decompositions exist.
