Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122790, here are decompositions:

13 + 122777 = 122790
29 + 122761 = 122790
37 + 122753 = 122790
47 + 122743 = 122790
71 + 122719 = 122790
89 + 122701 = 122790
97 + 122693 = 122790
127 + 122663 = 122790

Showing the first eight; more decompositions exist.
