Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18010, here are decompositions:

23 + 17987 = 18010
29 + 17981 = 18010
53 + 17957 = 18010
71 + 17939 = 18010
89 + 17921 = 18010
101 + 17909 = 18010
107 + 17903 = 18010
173 + 17837 = 18010

Showing the first eight; more decompositions exist.
