Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003906, here are decompositions:

17 + 1003889 = 1003906
89 + 1003817 = 1003906
149 + 1003757 = 1003906
173 + 1003733 = 1003906
227 + 1003679 = 1003906
317 + 1003589 = 1003906
389 + 1003517 = 1003906
443 + 1003463 = 1003906

Showing the first eight; more decompositions exist.
