Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051778, here are decompositions:

19 + 1051759 = 1051778
31 + 1051747 = 1051778
61 + 1051717 = 1051778
139 + 1051639 = 1051778
157 + 1051621 = 1051778
229 + 1051549 = 1051778
271 + 1051507 = 1051778
307 + 1051471 = 1051778

Showing the first eight; more decompositions exist.
