Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019782, here are decompositions:

11 + 1019771 = 1019782
41 + 1019741 = 1019782
53 + 1019729 = 1019782
59 + 1019723 = 1019782
83 + 1019699 = 1019782
89 + 1019693 = 1019782
233 + 1019549 = 1019782
251 + 1019531 = 1019782

Showing the first eight; more decompositions exist.
