Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164940, here are decompositions:

29 + 164911 = 164940
47 + 164893 = 164940
59 + 164881 = 164940
101 + 164839 = 164940
103 + 164837 = 164940
109 + 164831 = 164940
131 + 164809 = 164940
151 + 164789 = 164940

Showing the first eight; more decompositions exist.
