Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028938, here are decompositions:

101 + 1028837 = 1028938
191 + 1028747 = 1028938
257 + 1028681 = 1028938
269 + 1028669 = 1028938
359 + 1028579 = 1028938
467 + 1028471 = 1028938
797 + 1028141 = 1028938
809 + 1028129 = 1028938

Showing the first eight; more decompositions exist.
