Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168900, here are decompositions:

7 + 168893 = 168900
13 + 168887 = 168900
31 + 168869 = 168900
37 + 168863 = 168900
97 + 168803 = 168900
131 + 168769 = 168900
139 + 168761 = 168900
157 + 168743 = 168900

Showing the first eight; more decompositions exist.
