Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019810, here are decompositions:

79 + 1019731 = 1019810
97 + 1019713 = 1019810
109 + 1019701 = 1019810
163 + 1019647 = 1019810
193 + 1019617 = 1019810
277 + 1019533 = 1019810
307 + 1019503 = 1019810
331 + 1019479 = 1019810

Showing the first eight; more decompositions exist.
