Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17902, here are decompositions:

11 + 17891 = 17902
113 + 17789 = 17902
173 + 17729 = 17902
233 + 17669 = 17902
293 + 17609 = 17902
383 + 17519 = 17902
419 + 17483 = 17902
431 + 17471 = 17902

Showing the first eight; more decompositions exist.
