Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17904, here are decompositions:

13 + 17891 = 17904
23 + 17881 = 17904
41 + 17863 = 17904
53 + 17851 = 17904
67 + 17837 = 17904
97 + 17807 = 17904
113 + 17791 = 17904
157 + 17747 = 17904

Showing the first eight; more decompositions exist.
