Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019390, here are decompositions:

13 + 1019377 = 1019390
37 + 1019353 = 1019390
61 + 1019329 = 1019390
109 + 1019281 = 1019390
139 + 1019251 = 1019390
181 + 1019209 = 1019390
193 + 1019197 = 1019390
271 + 1019119 = 1019390

Showing the first eight; more decompositions exist.
