Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031828, here are decompositions:

19 + 1031809 = 1031828
67 + 1031761 = 1031828
97 + 1031731 = 1031828
151 + 1031677 = 1031828
199 + 1031629 = 1031828
307 + 1031521 = 1031828
349 + 1031479 = 1031828
367 + 1031461 = 1031828

Showing the first eight; more decompositions exist.
