Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047390, here are decompositions:

11 + 1047379 = 1047390
17 + 1047373 = 1047390
23 + 1047367 = 1047390
67 + 1047323 = 1047390
73 + 1047317 = 1047390
79 + 1047311 = 1047390
83 + 1047307 = 1047390
101 + 1047289 = 1047390

Showing the first eight; more decompositions exist.
