Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986810, here are decompositions:

31 + 986779 = 986810
43 + 986767 = 986810
61 + 986749 = 986810
73 + 986737 = 986810
103 + 986707 = 986810
151 + 986659 = 986810
193 + 986617 = 986810
211 + 986599 = 986810

Showing the first eight; more decompositions exist.
