Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966820, here are decompositions:

3 + 966817 = 966820
17 + 966803 = 966820
167 + 966653 = 966820
263 + 966557 = 966820
293 + 966527 = 966820
311 + 966509 = 966820
389 + 966431 = 966820
401 + 966419 = 966820

Showing the first eight; more decompositions exist.
