Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000928, here are decompositions:

7 + 1000921 = 1000928
67 + 1000861 = 1000928
79 + 1000849 = 1000928
151 + 1000777 = 1000928
277 + 1000651 = 1000928
307 + 1000621 = 1000928
349 + 1000579 = 1000928
421 + 1000507 = 1000928

Showing the first eight; more decompositions exist.
