Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008878, here are decompositions:

7 + 1008871 = 1008878
19 + 1008859 = 1008878
61 + 1008817 = 1008878
97 + 1008781 = 1008878
271 + 1008607 = 1008878
307 + 1008571 = 1008878
331 + 1008547 = 1008878
337 + 1008541 = 1008878

Showing the first eight; more decompositions exist.
