Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001906, here are decompositions:

67 + 1001839 = 1001906
97 + 1001809 = 1001906
109 + 1001797 = 1001906
163 + 1001743 = 1001906
193 + 1001713 = 1001906
223 + 1001683 = 1001906
277 + 1001629 = 1001906
313 + 1001593 = 1001906

Showing the first eight; more decompositions exist.
