Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061978, here are decompositions:

19 + 1061959 = 1061978
61 + 1061917 = 1061978
67 + 1061911 = 1061978
97 + 1061881 = 1061978
109 + 1061869 = 1061978
199 + 1061779 = 1061978
241 + 1061737 = 1061978
271 + 1061707 = 1061978

Showing the first eight; more decompositions exist.
