Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051838, here are decompositions:

19 + 1051819 = 1051838
79 + 1051759 = 1051838
199 + 1051639 = 1051838
331 + 1051507 = 1051838
367 + 1051471 = 1051838
379 + 1051459 = 1051838
421 + 1051417 = 1051838
547 + 1051291 = 1051838

Showing the first eight; more decompositions exist.
