Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978874, here are decompositions:

3 + 978871 = 978874
11 + 978863 = 978874
23 + 978851 = 978874
53 + 978821 = 978874
101 + 978773 = 978874
131 + 978743 = 978874
191 + 978683 = 978874
227 + 978647 = 978874

Showing the first eight; more decompositions exist.
