Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178850, here are decompositions:

19 + 178831 = 178850
31 + 178819 = 178850
37 + 178813 = 178850
43 + 178807 = 178850
97 + 178753 = 178850
157 + 178693 = 178850
211 + 178639 = 178850
223 + 178627 = 178850

Showing the first eight; more decompositions exist.
