Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001842, here are decompositions:

3 + 1001839 = 1001842
11 + 1001831 = 1001842
41 + 1001801 = 1001842
59 + 1001783 = 1001842
173 + 1001669 = 1001842
293 + 1001549 = 1001842
311 + 1001531 = 1001842
383 + 1001459 = 1001842

Showing the first eight; more decompositions exist.
