Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164988, here are decompositions:

107 + 164881 = 164988
149 + 164839 = 164988
151 + 164837 = 164988
157 + 164831 = 164988
167 + 164821 = 164988
179 + 164809 = 164988
199 + 164789 = 164988
281 + 164707 = 164988

Showing the first eight; more decompositions exist.
