Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003838, here are decompositions:

19 + 1003819 = 1003838
67 + 1003771 = 1003838
97 + 1003741 = 1003838
109 + 1003729 = 1003838
127 + 1003711 = 1003838
211 + 1003627 = 1003838
229 + 1003609 = 1003838
331 + 1003507 = 1003838

Showing the first eight; more decompositions exist.
