Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028726, here are decompositions:

43 + 1028683 = 1028726
79 + 1028647 = 1028726
109 + 1028617 = 1028726
157 + 1028569 = 1028726
337 + 1028389 = 1028726
397 + 1028329 = 1028726
409 + 1028317 = 1028726
463 + 1028263 = 1028726

Showing the first eight; more decompositions exist.
