Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179870, here are decompositions:

37 + 179833 = 179870
43 + 179827 = 179870
127 + 179743 = 179870
151 + 179719 = 179870
181 + 179689 = 179870
199 + 179671 = 179870
211 + 179659 = 179870
277 + 179593 = 179870

Showing the first eight; more decompositions exist.
