Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162004, here are decompositions:

5 + 161999 = 162004
47 + 161957 = 162004
83 + 161921 = 162004
131 + 161873 = 162004
173 + 161831 = 162004
197 + 161807 = 162004
233 + 161771 = 162004
251 + 161753 = 162004

Showing the first eight; more decompositions exist.
