Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17910, here are decompositions:

7 + 17903 = 17910
19 + 17891 = 17910
29 + 17881 = 17910
47 + 17863 = 17910
59 + 17851 = 17910
71 + 17839 = 17910
73 + 17837 = 17910
83 + 17827 = 17910

Showing the first eight; more decompositions exist.
