Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055878, here are decompositions:

11 + 1055867 = 1055878
107 + 1055771 = 1055878
137 + 1055741 = 1055878
269 + 1055609 = 1055878
281 + 1055597 = 1055878
311 + 1055567 = 1055878
347 + 1055531 = 1055878
389 + 1055489 = 1055878

Showing the first eight; more decompositions exist.
