Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180098, here are decompositions:

97 + 180001 = 180098
109 + 179989 = 180098
151 + 179947 = 180098
181 + 179917 = 180098
199 + 179899 = 180098
271 + 179827 = 180098
277 + 179821 = 180098
349 + 179749 = 180098

Showing the first eight; more decompositions exist.
