Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179800, here are decompositions:

83 + 179717 = 179800
107 + 179693 = 179800
113 + 179687 = 179800
149 + 179651 = 179800
167 + 179633 = 179800
197 + 179603 = 179800
227 + 179573 = 179800
251 + 179549 = 179800

Showing the first eight; more decompositions exist.
