Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986878, here are decompositions:

29 + 986849 = 986878
41 + 986837 = 986878
59 + 986819 = 986878
149 + 986729 = 986878
281 + 986597 = 986878
311 + 986567 = 986878
359 + 986519 = 986878
401 + 986477 = 986878

Showing the first eight; more decompositions exist.
