Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179868, here are decompositions:

19 + 179849 = 179868
41 + 179827 = 179868
47 + 179821 = 179868
61 + 179807 = 179868
67 + 179801 = 179868
89 + 179779 = 179868
131 + 179737 = 179868
149 + 179719 = 179868

Showing the first eight; more decompositions exist.
