Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001816, here are decompositions:

7 + 1001809 = 1001816
19 + 1001797 = 1001816
73 + 1001743 = 1001816
103 + 1001713 = 1001816
157 + 1001659 = 1001816
223 + 1001593 = 1001816
229 + 1001587 = 1001816
349 + 1001467 = 1001816

Showing the first eight; more decompositions exist.
