Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996878, here are decompositions:

7 + 996871 = 996878
19 + 996859 = 996878
31 + 996847 = 996878
37 + 996841 = 996878
67 + 996811 = 996878
97 + 996781 = 996878
139 + 996739 = 996878
229 + 996649 = 996878

Showing the first eight; more decompositions exist.
