Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001860, here are decompositions:

29 + 1001831 = 1001860
53 + 1001807 = 1001860
59 + 1001801 = 1001860
137 + 1001723 = 1001860
173 + 1001687 = 1001860
191 + 1001669 = 1001860
239 + 1001621 = 1001860
311 + 1001549 = 1001860

Showing the first eight; more decompositions exist.
