Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001872, here are decompositions:

41 + 1001831 = 1001872
71 + 1001801 = 1001872
89 + 1001783 = 1001872
149 + 1001723 = 1001872
233 + 1001639 = 1001872
251 + 1001621 = 1001872
461 + 1001411 = 1001872
491 + 1001381 = 1001872

Showing the first eight; more decompositions exist.
