Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986720, here are decompositions:

3 + 986717 = 986720
13 + 986707 = 986720
61 + 986659 = 986720
79 + 986641 = 986720
103 + 986617 = 986720
127 + 986593 = 986720
139 + 986581 = 986720
151 + 986569 = 986720

Showing the first eight; more decompositions exist.
