Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940878, here are decompositions:

7 + 940871 = 940878
61 + 940817 = 940878
97 + 940781 = 940878
139 + 940739 = 940878
151 + 940727 = 940878
157 + 940721 = 940878
229 + 940649 = 940878
271 + 940607 = 940878

Showing the first eight; more decompositions exist.
