Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171604, here are decompositions:

113 + 171491 = 171604
131 + 171473 = 171604
137 + 171467 = 171604
263 + 171341 = 171604
311 + 171293 = 171604
353 + 171251 = 171604
401 + 171203 = 171604
443 + 171161 = 171604

Showing the first eight; more decompositions exist.
