Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136780, here are decompositions:

3 + 136777 = 136780
11 + 136769 = 136780
29 + 136751 = 136780
41 + 136739 = 136780
47 + 136733 = 136780
53 + 136727 = 136780
71 + 136709 = 136780
89 + 136691 = 136780

Showing the first eight; more decompositions exist.
