Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536780, here are decompositions:

3 + 536777 = 536780
7 + 536773 = 536780
31 + 536749 = 536780
37 + 536743 = 536780
61 + 536719 = 536780
103 + 536677 = 536780
109 + 536671 = 536780
271 + 536509 = 536780

Showing the first eight; more decompositions exist.
