Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051782, here are decompositions:

19 + 1051763 = 1051782
23 + 1051759 = 1051782
73 + 1051709 = 1051782
139 + 1051643 = 1051782
163 + 1051619 = 1051782
181 + 1051601 = 1051782
191 + 1051591 = 1051782
211 + 1051571 = 1051782

Showing the first eight; more decompositions exist.
