Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001656, here are decompositions:

17 + 1001639 = 1001656
107 + 1001549 = 1001656
197 + 1001459 = 1001656
269 + 1001387 = 1001656
353 + 1001303 = 1001656
389 + 1001267 = 1001656
419 + 1001237 = 1001656
479 + 1001177 = 1001656

Showing the first eight; more decompositions exist.
