Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019290, here are decompositions:

17 + 1019273 = 1019290
23 + 1019267 = 1019290
29 + 1019261 = 1019290
53 + 1019237 = 1019290
113 + 1019177 = 1019290
197 + 1019093 = 1019290
257 + 1019033 = 1019290
353 + 1018937 = 1019290

Showing the first eight; more decompositions exist.
