Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165030, here are decompositions:

29 + 165001 = 165030
31 + 164999 = 165030
43 + 164987 = 165030
67 + 164963 = 165030
137 + 164893 = 165030
149 + 164881 = 165030
191 + 164839 = 165030
193 + 164837 = 165030

Showing the first eight; more decompositions exist.
