Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492164, here are decompositions:

7 + 31492157 = 31492164
71 + 31492093 = 31492164
73 + 31492091 = 31492164
83 + 31492081 = 31492164
97 + 31492067 = 31492164
103 + 31492061 = 31492164
113 + 31492051 = 31492164
131 + 31492033 = 31492164

Showing the first eight; more decompositions exist.
