Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171790, here are decompositions:

29 + 171761 = 171790
71 + 171719 = 171790
83 + 171707 = 171790
131 + 171659 = 171790
137 + 171653 = 171790
149 + 171641 = 171790
173 + 171617 = 171790
251 + 171539 = 171790

Showing the first eight; more decompositions exist.
