Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171404, here are decompositions:

3 + 171401 = 171404
151 + 171253 = 171404
241 + 171163 = 171404
313 + 171091 = 171404
397 + 171007 = 171404
433 + 170971 = 171404
523 + 170881 = 171404
547 + 170857 = 171404

Showing the first eight; more decompositions exist.
