Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061780, here are decompositions:

7 + 1061773 = 1061780
43 + 1061737 = 1061780
73 + 1061707 = 1061780
103 + 1061677 = 1061780
151 + 1061629 = 1061780
157 + 1061623 = 1061780
163 + 1061617 = 1061780
211 + 1061569 = 1061780

Showing the first eight; more decompositions exist.
