Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012808, here are decompositions:

19 + 1012789 = 1012808
37 + 1012771 = 1012808
109 + 1012699 = 1012808
151 + 1012657 = 1012808
211 + 1012597 = 1012808
397 + 1012411 = 1012808
409 + 1012399 = 1012808
439 + 1012369 = 1012808

Showing the first eight; more decompositions exist.
