Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019426, here are decompositions:

3 + 1019423 = 1019426
13 + 1019413 = 1019426
73 + 1019353 = 1019426
97 + 1019329 = 1019426
229 + 1019197 = 1019426
307 + 1019119 = 1019426
349 + 1019077 = 1019426
367 + 1019059 = 1019426

Showing the first eight; more decompositions exist.
