Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171902, here are decompositions:

13 + 171889 = 171902
79 + 171823 = 171902
103 + 171799 = 171902
109 + 171793 = 171902
139 + 171763 = 171902
223 + 171679 = 171902
229 + 171673 = 171902
331 + 171571 = 171902

Showing the first eight; more decompositions exist.
