Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001870, here are decompositions:

31 + 1001839 = 1001870
61 + 1001809 = 1001870
73 + 1001797 = 1001870
127 + 1001743 = 1001870
157 + 1001713 = 1001870
211 + 1001659 = 1001870
241 + 1001629 = 1001870
277 + 1001593 = 1001870

Showing the first eight; more decompositions exist.
