Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 956820, here are decompositions:

19 + 956801 = 956820
31 + 956789 = 956820
61 + 956759 = 956820
71 + 956749 = 956820
97 + 956723 = 956820
107 + 956713 = 956820
131 + 956689 = 956820
233 + 956587 = 956820

Showing the first eight; more decompositions exist.
