Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171382, here are decompositions:

41 + 171341 = 171382
53 + 171329 = 171382
83 + 171299 = 171382
89 + 171293 = 171382
131 + 171251 = 171382
149 + 171233 = 171382
179 + 171203 = 171382
251 + 171131 = 171382

Showing the first eight; more decompositions exist.
