Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166898, here are decompositions:

31 + 166867 = 166898
37 + 166861 = 166898
157 + 166741 = 166898
229 + 166669 = 166898
241 + 166657 = 166898
271 + 166627 = 166898
331 + 166567 = 166898
337 + 166561 = 166898

Showing the first eight; more decompositions exist.
