Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122800, here are decompositions:

11 + 122789 = 122800
23 + 122777 = 122800
47 + 122753 = 122800
59 + 122741 = 122800
107 + 122693 = 122800
137 + 122663 = 122800
149 + 122651 = 122800
191 + 122609 = 122800

Showing the first eight; more decompositions exist.
