Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011778, here are decompositions:

29 + 1011749 = 1011778
41 + 1011737 = 1011778
59 + 1011719 = 1011778
101 + 1011677 = 1011778
107 + 1011671 = 1011778
137 + 1011641 = 1011778
179 + 1011599 = 1011778
191 + 1011587 = 1011778

Showing the first eight; more decompositions exist.
