Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136800, here are decompositions:

23 + 136777 = 136800
31 + 136769 = 136800
47 + 136753 = 136800
61 + 136739 = 136800
67 + 136733 = 136800
73 + 136727 = 136800
89 + 136711 = 136800
107 + 136693 = 136800

Showing the first eight; more decompositions exist.
