Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001830, here are decompositions:

23 + 1001807 = 1001830
29 + 1001801 = 1001830
47 + 1001783 = 1001830
107 + 1001723 = 1001830
191 + 1001639 = 1001830
281 + 1001549 = 1001830
383 + 1001447 = 1001830
419 + 1001411 = 1001830

Showing the first eight; more decompositions exist.
