Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654878, here are decompositions:

5 + 8654873 = 8654878
41 + 8654837 = 8654878
107 + 8654771 = 8654878
149 + 8654729 = 8654878
257 + 8654621 = 8654878
269 + 8654609 = 8654878
389 + 8654489 = 8654878
431 + 8654447 = 8654878

Showing the first eight; more decompositions exist.
