Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179918, here are decompositions:

19 + 179899 = 179918
97 + 179821 = 179918
139 + 179779 = 179918
181 + 179737 = 179918
199 + 179719 = 179918
229 + 179689 = 179918
337 + 179581 = 179918
421 + 179497 = 179918

Showing the first eight; more decompositions exist.
