Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047878, here are decompositions:

19 + 1047859 = 1047878
37 + 1047841 = 1047878
127 + 1047751 = 1047878
157 + 1047721 = 1047878
211 + 1047667 = 1047878
229 + 1047649 = 1047878
367 + 1047511 = 1047878
379 + 1047499 = 1047878

Showing the first eight; more decompositions exist.
