Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 955820, here are decompositions:

7 + 955813 = 955820
13 + 955807 = 955820
43 + 955777 = 955820
109 + 955711 = 955820
127 + 955693 = 955820
163 + 955657 = 955820
337 + 955483 = 955820
379 + 955441 = 955820

Showing the first eight; more decompositions exist.
