Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019686, here are decompositions:

23 + 1019663 = 1019686
29 + 1019657 = 1019686
47 + 1019639 = 1019686
137 + 1019549 = 1019686
149 + 1019537 = 1019686
233 + 1019453 = 1019686
263 + 1019423 = 1019686
347 + 1019339 = 1019686

Showing the first eight; more decompositions exist.
