Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986780, here are decompositions:

13 + 986767 = 986780
31 + 986749 = 986780
43 + 986737 = 986780
61 + 986719 = 986780
73 + 986707 = 986780
139 + 986641 = 986780
163 + 986617 = 986780
181 + 986599 = 986780

Showing the first eight; more decompositions exist.
