Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051788, here are decompositions:

7 + 1051781 = 1051788
29 + 1051759 = 1051788
41 + 1051747 = 1051788
71 + 1051717 = 1051788
79 + 1051709 = 1051788
139 + 1051649 = 1051788
149 + 1051639 = 1051788
167 + 1051621 = 1051788

Showing the first eight; more decompositions exist.
