Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061778, here are decompositions:

5 + 1061773 = 1061778
7 + 1061771 = 1061778
19 + 1061759 = 1061778
41 + 1061737 = 1061778
61 + 1061717 = 1061778
71 + 1061707 = 1061778
79 + 1061699 = 1061778
89 + 1061689 = 1061778

Showing the first eight; more decompositions exist.
