Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009838, here are decompositions:

19 + 1009819 = 1009838
31 + 1009807 = 1009838
97 + 1009741 = 1009838
211 + 1009627 = 1009838
229 + 1009609 = 1009838
307 + 1009531 = 1009838
331 + 1009507 = 1009838
337 + 1009501 = 1009838

Showing the first eight; more decompositions exist.
