Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042808, here are decompositions:

127 + 1042681 = 1042808
199 + 1042609 = 1042808
211 + 1042597 = 1042808
409 + 1042399 = 1042808
439 + 1042369 = 1042808
499 + 1042309 = 1042808
541 + 1042267 = 1042808
709 + 1042099 = 1042808

Showing the first eight; more decompositions exist.
