Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171788, here are decompositions:

31 + 171757 = 171788
109 + 171679 = 171788
151 + 171637 = 171788
229 + 171559 = 171788
271 + 171517 = 171788
307 + 171481 = 171788
349 + 171439 = 171788
619 + 171169 = 171788

Showing the first eight; more decompositions exist.
